How does Carl decide what goes native and what does?

Why switch, and not case ?

append got native too :-) well, imo if you use something often, in 
mezzanine level, then it could be brought to native level? Imo it 
could be even profilet, to know if the speed gain is there or not, 
no?

I don't think it's very wise to implement 'switch native in 2.7 when 
it can broke old code. Save it for 3.0, why not, but why breaking 
the compatibility, when it's not necesary?

perhaps it's a sneaky way of testing R3 code? :-)

you can always redefine it back again.

I am with Rebolek here - 2.x family should stay as separate branch, 
usable in what it offers, no new experiments.

but maybe compatibility issue here is not a problem?

Pekr: older switch evaluates values , newer does not 
>>b: [print "!"] switch 1 [1 b]
prints "!" in older versions, returns none! in 2.7.2

that is rather big change in behavior, no? But it was probably discussed 
here enough, so that 2.7.2 is kind of consensus of developers opinion?

yes it was discussed,

anton, should we rambo it as it is?

anton, (about your patch)

anton, I tried TOGs, BTNs and overlapping TOGs and they all work 
without this problem now. looks OK to me.

Rebolek you make a good point about the switch.  Maybe we should 
modify it so that it can find block! or type? block!  - of course 
it is native right now so I have no idea what that means for the 
code.

Which I don't know if that is very desirable either as some may want 
just the block returned and not evaluate as it would now if in your 
example the b were in build in the case such as [1 [b]]         But 
in any event you can get the effect you want with the current switch 
by doing this:  do switch 1 [1 [b]]

Henrik, no, I'll clean it up first. I just thought you might have 
needed it for something. It's in my editor so I ought not to forget 
about it. :)

anton, ok. it would just be very nice to get this fixed properly. 
I've had complaints over this a few times now.

Ok, so it's not just a frivolous claim :) Don't worry, I won't forget.

WTF new switch doesn' evaluate?  that was the point of the previous 
switch.  none of my last 5 years of code will now work.

Example ?

what's the point of changing switch in 2.7?

To make it better ?

at what cost?

This works for me:
>> switch 1 [1 [print "hello"]]
hello

give me a minute... I'll do a real test.

ok I just looked at the above example and yes it makes sense now... 
 I thought it didn't evaluate the content of the block.

so since it does evaluate, yes my code seems to work pretty well 
under 2.7 GLayout presents no artifacts, and liquid will run a little 
faster with newer switch.

Graham, CASE has always been a native. SWITCH needs to be native 
for the BREAK problem I mentioned (otherwise /ALL makes the function 
rather inefficient)

Rebolek: if it really breaks important code, we will revert it back. 
The request for changes to SWITCH was in RAMBO.

why did changing the executable rebol.exe to v2.7 force me to go 
throught setup of user again?

especially since it didn't even change the content of the user.r 
file... but now it accepts it?

Henrik, I published the TOG bug to RAMBO. (It didn't really need 
much cleaning. I just checked that the TOG feel was used only by 
TOG.)

wonderful! thanks :-)

Gabriele: OK, that's reasonable

I have a slightly modified help, that does not evaluate functions 
in objects and ports and that also dumps ports like objects.

Is there interest in including in the new release?

help/secure a/handler/set-modes
    there is a function inside an object or port
USAGE:
    A/HANDLER/SET-MODES port modes

DESCRIPTION:
    (undocumented)
     A/HANDLER/SET-MODES is a function value.

ARGUMENTS:
     port -- An open port spec (Type: any)
     modes -- A mode block (Type: any)

yes... please send this to Carl

very cool!

I put it into Rambo and into the library at rebol.org, as Carl promised 
it already once to include it in one of the former realeses.

I fixed some problems with blocks

scaling info.gif (which has an alpha channel) gives funky red and 
yellow stripes when specifying 2 or 4 points (but not 1 point).

This bug seems to have been introduced in View 1.3.2 and is still 
present in View 2.7.4
	  

 window: layout [b: box sky effect [draw [image info.gif 0x0 49x48]] 
 mag: box 600x600] 
	mag/image: to-image b 
	view window

It doesn't appear to be in the bug database.

I've been investigating the bug above with this script:

do read http://anton.wildit.net.au/rebol/view/draw/agg/image-fit.r

anton, testing both on XP and OSX. the bug does not appear on OSX, 
though colors are odd there due to a known bug.

another known bug, that is

it could be that the odd colors are simply hiding your bug, though. 
:-)

It looks like it also has the alpha channel problem.
