could you try an STRACE on both Debian and Fedora to see what's really 
different?

gabriele: will do later today

Hangs

Note the: open("/etc/termcap", O_RDONLY)          = -1 ENOENT (No

is it the same on other systems?

also that select seems to be waiting on nothing?

can you read computers mind? :))

google: /etc/termcap debian

http://packages.debian.org/stable/oldlibs/termcap-compat

apt-get install termcap-compat

console :))

Big thanks!

:-)

it's worth reporting though, maybe can be added to the docs, or can 
be fixed by falling back some default if termcap is not there...

Maybe some hint when not quiet? "Termcap failed, see http://***for 
suggestions"

#3436 OK - 2.5.58.3.1 on WinXP

I just noticed:

mold ['return:]  ;== "['return]"    <-- missing the colon ":"

mold/all does not help.

simplifies to:

mold 'return:   ;== "return"   (note no leading single quote, we 
are expecting that as normal though.)

mold 'hello:   ;== "hello"     (same idea)

lit-words like 'hello:  only just became valid recently (since View 
1.2.55.3.1)

I don't see any Rambo ticket for this issue (searched rambo for "word", 
looked at all 36 items.)

But, can somebody confirm if it is a bug or not ?

It would appear to me to be a bug.

(not that that means anything. ;-)

>> a: 'hello:
== hello


The colon seems to be removed. So it's a lit-word thing, nothing 
with mold, I guess.

actually, ['return:] should be marked as a bug, because you are trying 
to create a "cross" between lit- and set-word

what type should it have? - the interpreter seems to take it as a 
set-word

... wrong, the interpreter takes it as a lit-word

that should probably throw a syntax error... anyone submitting it?

What if you want to generate code, eg:
>> reduce ['return: [integer!]]

== [return [integer!]]   ;  I wanted this --->  [return: [integer!]]

I know you can use to-set-word, but that's not very concise is it 
?

But as Ladislav pointed out above, it seems that  'return:  would 
have to be interpreted as a new datatype ( a lit-set-word! )

Maybe it's not worth it now to add such a new datatype.. or maybe 
it does not hurt at all, speedwise, because if the parser is going 
to catch the syntax error above then it may as well just assign the 
new datatype. The cost, I think, will be in maintaining a new datatype; 
bug-testing, docs etc.  So ok, I agree with Gabriele.

Ok, I posted RAMBO Ticket #-131   (waiting to be reviewed)

Anton: What if you want to generate code, eg:
>> reduce ['return: [integer!]]

try reduce [first [return:] [integer!]]
