World: r3wp

i guess names msg are here to construct file trees

Speaking of which, what do yo think of my /into option proposal?

Nothing special, it's an new feature, so it's wellcome.

I'll take that as neutral :)

yep :)

About FIND-ALL, would it not always return the result as indexes 
from the original block?

The trick with FIND-ALL is that it doesn't reeturn anything - it 
executes a code block wioth each find.

FIND-ALL is like FORALL, but with FIND.

Then I think the name is misleading. Or will there be a FIND/ALL?

There may be, and it could be useful with /skip.

FORFIND perhaps?

That could be, or as a step argument to FOR.

(who says step must be a constant?)

then again, how would one pass it. it seems that FOR already uses 
series! as step input.

eh guys, if you continue like that, i guess you will rediscover parse

This kind of function is usually easier to implement as a mezzanine.

Steeve, I know. You can do everything with PARSE in only 10 times 
as much code as with a single mezz. :-)

Parse - we first need all those handy enchancements being implemented 
:-)

R2 backports of the R3 reflection functions are now done.

So - are we heading towards new R2 release?

That's REFLECT and its associated *-OF functions. Yes, gradually, 
as R3 gets fuurther along. The backports can be used with existing 
releases though - I'm bundling them all into %r2-forward.r.

I also backported CAUSE-ERROR, which triggers errors safely.

Also the proposed QUOTE and ACCUMULATE.

quote ?

accumulate -> cumul (shorter name)

QUOTE is a Peta special, a simple function to perform a nasty trick 
in as little code as possible. It blocks evalation :)

; R3 version
quote: func [
	"Returns the value passed to it without evaluation."
	:value [any-type!]
] [
	:value
]

; R2 version
quote: func [
	"Returns the value passed to it without evaluation."
	:value [any-type!]
] [
	get/any 'value
]

It's like the Scheme function of the same name.

evalation -> evaluation

CUMUL is not an English word (but let me check). I picked ACCUMULATE 
because it is the industry standard (for procedural langs).

oh sorry it's french (i tried)

We are not going the Perl 6 route :)

I'm checking a thesaurus.

and ACCU ?

GATHER perhaps?

http://en.wikipedia.org/wiki/ACCU

BrianH, check #1804, for a GATHER function that does something else.

That sounds like a better function to call GATHER. ACCUMULATE will 
get called less than that.

It could use the /into option though.

With all of these collection synonym functions it will be interesting 
to keep them straight.

Use FORALL for the R3 version of GATHER - FORALL is faster than FOREACH 
in R3.

ASSEMBLE might be a nice word to reserve.

Could be disturbing for beginners, a same thing can be writed  using 
so many various ways with the tons of mezz we have now.

Yeah. For an assembler :) We want reserve COMPILE too :D

Steeve, you have a point. For a couple of years, I would write mezzanines 
for things that already existed in R2, but hadn't noticed.

ahah, shame on you ;-)

I'm converting GATHER to mezzanine/library code standards now. We'll 
probably put all of these is an advanced series manipulation library 
module.

types-of is ugly Brian :)

You have no idea. TYPES-OF was the only reflector that had no corresponding 
hack in R2. I had to do it from scratch.

Mezzanine-quality version of Henrik's GATHER, R3 version:

gather: func [
	"Get the values of a given field from all objects in a block."
	block [block!]
	word [word!]

 /into "Insert into a buffer instead (returns position after insert)"
	output [series!] "The buffer series (modified)"
][
	unless output [output: make block length? block]
	forall block [
		all [
			object? block/1
			in block/1 word
			output: insert/only output select block/1 word
		]
	]
	either into [output] [head output]
]

Has the spec for make function! been changed on purpose in R3? Is 
for what reason?
