; what is the rationale, I wonder of the difference
>> lit-word? first [ 'thang thing]  
== true
>> lit-word? 'thang
== false
>> type? first ['thang thing]
== lit-word!
>> type? 'thang
== word!

type? first ['thang]
'thang is not being evaluated

type? 'thang

'thang is being evaluated. The result of that evaluation is a word!

.....But with 'reduce, 'thang is being evaluated, so:
    type? first reduce ['thang]
    == word!

I can't believe I missed all those REBOL tutorials available on Youtube 
by Nick Antoniacco. Here's the complete list, in case newbies missed 
them too:

http://musiclessonz.com/rebol_video_links.html

Interesting guy http://rockfactory.us/Teachers.html

He is the top one "Nick"

Didn't RT link to those from REBOL.com at some point? If not, they 
really should.

looking at source of 'send, am I right, if there is an error executing 
send, than the port is not closed, this will leave a lot of open 
connections when batching?

Ports are closed when the garbage collector gets them. If you are 
batch sending, the next time you call the SEND function it will assign 
none to the smtp-port local variable, rendering the previous reference 
assigned to that variable into garbage. The next time RECYCLE is 
run, any open ports in the garbage will be closed.

ok, but between recycles, I could reach the maximum connections limit 
of the smtp server?

also, 'send should probably return a value of type logic!

Recycle yourself if you're worried. Interesting idea on the return 
value.

Thanks BrianH, I'm trying to find a bug, I get random port none not 
open errors but they appear randomly everywhere, only thing sure 
is they come only after using 'send , but it may be word! conflict, 
variable rewrite, etc.. just maybe someone has a better idea where 
to look for.. 8/

looks like an asynchronous event error popping in the middle of execution 
of other code, possible??

like this error:
code: 501
description: access error, Port none not open
near:
[if none? i [return none] 
either
]
where: confirm

or

code: 501
description: access error, Port none not open
near:
[if empty? block: reduce block]
where: confirm


oly thing in common, is where: confirm and that I see only in net-utils, 
any idea ?

even had a recycle..
code: 501

here is the net-log, a couple of this (no problem)::

error code: 501

note the difference that seams to trigger the problem is the first 
line, the 'quit, where does it come from?

;-- Send as an SMTP batch or individually addressed:
        smtp-port: open [scheme: 'esmtp]
        either only [ ; Only one message to multiple addrs

                ; remove non-email values

        ] [
                foreach addr address [
                        if email? addr [

                ]
        ]
        close smtp-port

the port is closed in the last line of send - am i missing something?

it may not be closed in case of errors, but as Brian said, the GC 
will catch that eventually (though maybe we should TRY and rethrow 
the error)

about the above error - it may be an out-of-order event indeed. now 
the problem is finding a simple way to reproduce it.

Hi Henrik, I found Nicks youTube tutorials to be very useful when 
I was searching for stuff. Great help!

I'm inviting a friend of mine here, he is another brilliant langauge 
designer, I'll invite him as Fork (his real name is Brian, but we 
have enough Brians around here.

We're taking over :)

Call him Brain instead ...

That would conflict with even more people here :)

Where ?

so is this in a REBOL Survival Guide somewheres?

{  from guys on CORE }
is as good as
comment { 
so is this in a REBOL Survival Guide somewheres?
}
feelin' foolish as another 'good' idea meets my second cuppa java

have to be careful with using { ... } to comment things out though.. 
I wanted to teporarily remove a block of code from a function, but 
I didn't think of that it was the last part of the function so the 
string got returned instead of the real value I wanted :)

ODE
so I though mebbe
;{
 which would only end at a
;}
as }; will not do ...
To take a page from Snobol

  both would have to be unindented, i.e., occupy first and second char 
  of the line

I live in curly-brace land in CURL and a missing brace becomes a 
headache even in a editor with a scroll-u-there brace-matcher

I try never to repress my silly ideas as some have been winners (time 
and $$$ for my employers, true ... but all the same )

It does mean messing with the shift key which is un-rebolish
But I can't see suggesting
;[
block-comment code falls in here
;]
In CURL we have tag-matching using
|tag-this#
there will not be a duplicate tag until we reach
#tagthis|
|| where |# until #| are vulnerable

|| I ask developer sto single line comment with double-bars but someone 
has to use
|# multi-line comment on a single line to show they know how #|

but IF'n 
;[

   fell in the first two chars of a line and ended in first 2 chars 
   at (no shift key to reach { and } )
;]

mm..,
>> new-line [
[    1
[    ] false
>>   [1
]
shouldn't that return [1] ?

That's a known bug, see  http://www.rebol.net/cgi-bin/rambo.r?id=3902

Hi All, what's happening with Rebol 3?

REBOL 3 as a product, or this world? Well, you can find what is currently 
going on on rebol.com site, rebol 3 section. To summarize - RT is 
revising VID3 design (you might notice extensive blogging about the 
topic). There are also few features being considered for the core 
language, in order to make some constructs more easier/natural.

Once VID3 goes to beta, we will see new styles added, and View kernel 
fixes/improvements, to become beta too. Just after that, rebservices 
will be revised, in order for DevBase to go fully public, and R3 
source codes being uploaded into it. Then community can start porting 
open-source parts of REBOL to the platform of their wish, or the 
community can start to improve/fix those parts ...

temporary fix for bug/3902:
  a: [a                       
[    ]
;   [a
]
  a: new-line/all a off       
;   [a
]

  a: [a                       
[    ]
;   [a
]
  a: new-line/all copy a off
;   [a]

I'm stuck, teaching rebol to my girlfriend, I come across this and 
really as per definition I would expect to get [1] as result and 
not 1

  ? switch
USAGE:
    SWITCH value cases /default case /all 

DESCRIPTION:
     Selects a choice and evaluates the block that follows it.
     SWITCH is a native value.

ARGUMENTS:
     value -- Value to search for. (Type: any)
     cases -- Block of cases to search. (Type: block)

REFINEMENTS:
     /default
         case -- Default case if no others are found. (Type: any)
     /all -- Evaluates all matches (not just first one).
  switch/default 2 [][1] 
;   1
  switch/default 2 [] 1 
;   1

If the default case is a block, it is evaluated -- see: source switch

Thanks Chris, but then I would say it is either inconsistent or the 
description need some refinement

Why is it inconsistent?

>> do [1]
== 1
>> do 1
== 1

Well, you just pointed out that DO is inconsistent as well. As to 
how harmfully unexpected that is is another question. It obviously 
confused Will. Such things can be a problem, because there can be 
a loss of information. You get the same output from two different 
inputs, which can't be reversed.
