Updated to latest sources and a build is now inside as well.

Ah... map-event is the old map-inner native function

FACES-OF:FACES? preferences - the current count is 3 (developers 
- Cyphre, Ladislav, Henrik) : 3 ( Anton, Pekr, Oldes)

Oldes, I agree about the slight inappropriateness of back-face? next-face? 
having the '?'. However, I also don't like much the same names without 
the '?', as I used such words as variables in some algorithms. I 
tentatively suggest back-face-of next-face-of.

Anton, that might be a good idea.

I totally agree with you, Anton. I don't care that the world is longer 
if it improves readability of the code.

Oldes: there are a number of REBOL functions with a ? that return 
something other than boolean - length? and type? immediately spring 
to mind!
I can see that they would be more meaningful if they were called 
length-of and type-of  though.

They're also exceptions to the general rule, because the word without 
? is used too much as a variable or another function, as Anton says

Re: "They're also exceptions to the general rule" - the general rule 
*is* to use the question mark for such functions, though. The FACES-OF 
"convention" is not a REBOL convention. In fact, it is more like 
a C convention.

Ladislav: and what about words-of, values-of? Those did not exist 
in R2, but were added to R3. Faces-of fits that naming scheme ....
having consistent naming conventions across the board is imo always 
a tough call. Naturally I can understand, why you have selected short 
"faces", and adding question mark ...

Even in R2 we had maximum-of and minimum-of.
In R3 A110 we have 8 "-of" words and 16 non-logic! "?" words (+4 
"?" console convenience words).

I prefer the *-of naming, even if they might get complaints about 
not being reflectors (most of the -of words are reflectors).
Andreas

[4730]
Quite a few of the 16 existing "?" non-logic! words fall in the backwards-compatibility 
category (e.g. exists? index? info? length? modified? offset? size? 
type?).
BrianH

[4731x3]
Some of the ? words won't be able to be changed because of backwards 
compatibility (this is a #667 situation, not a #666).
We could add new words in addition to the old, but not get rid of 
the old. At least that's the policy (so far).
EXISTS? is used in conditional expressions, so it is not completely 
non-logic. I am not sold on the ? equals logic rule though; to me, 
? always meant question.
Anton
25-Dec-2010
[4734x2]
EXISTS? originally returned only logic, didn't it? So its evolution 
into more than just logic should also be considered a backwards compatibility 
legacy situation, I think.
I don't mind '?' being use to indicate a question, but I think the 
"-of" words more accurately reflect what information is being extracted 
FACES?
 - it's like  "huh?" - it's vague, someone's secret language.

(Maximum-of and minimum-of were poorly named; I wanted them changed 
to 'at-maximum(-of)' etc since they return the series at the index.)

Just a warning.
Don't be seduced by the Dark Side of the Force. 

It's what I dislike the most in all actual popular languages. I mean 
, the bad habit to outrageously extend the names of variables and 
method.

The exact meaning of variables and methods is given by the context 
of the use case.
That's why they don't need to be over explicit.
And If you have any doubt, you can use HELP, at least in Rebol.

Agreed, Steeve, I'm OK with giving a +1 to the magic words method.
Steeve

In human languages, words are almost all polysemous. The true meanings 
of words is given by the context.

Carl was able to expel all the horrors syntactic found in other languages. 
So we can almost read code like a human language.
Do not lose this goal, if you can.

+1 FACES?


What would a logic mean here? That there are faces? Well, it's a 
GUI thing... if than maybe FACE? could be ambigous.
Steeve

[4740]
Btw, I vote to keep FACES?.

When i see ? in a word's name, i know it may be a boolean or a calculated 
value (actually a function).
If the context is not clear enough, I invoke HELP.

Actually, I would have choose the name CHILDS. It's more polymorphic, 
and it can apply on faces or gobs.

pyromaniac vandal.
Returning (with some effort) to serious consideration of your argument; 
I'm in agreement (how could I not), but I would like to point out 
that it's a bit like a slippery slide argument: if I accept to add 
just a few more characters (? -> -of) then I'm on the road to creating 
the API with the most unwieldy extra long function names as found 
in other languages (without the utility of Rebol contexts at their 
disposal).

It was just a warning.
The Devil is in the details. 
-of

 could be the devil seed and give birth to abominations, like: get-faces-of-a-face
But I am conforted now ;-)

Just throwing something out here (as I'm not actively involved in 
R3 and mostly lurk):  I see "-of" as a "what" or "what are" type 
of question, while "?" more like "what is" (and all the rest) type 
of question.
(does it) exist?
(what is the) length?
(what is the) size?
(when was it) modified?
vs
(what are the) faces-of
(what are the) values-of

Then of course, minimum-of and maximum-of break this idea:
(what is the) minimum-of
But this works just as well IMO:
(what is the) minimum?


So looking at that, I'd consider the "?" or "-of" question to not 
so much be based on logic values, but whether it returns a single 
value, or a list of values.
So, +1 for FACES-OF here
Steeve

What informs about a single value or a list is the use of plural 
in the name.

I've always seen that as incidental, not the meaning, but I guess 
I can see how it works.

FACES? : FACES-OF = 5:6 currently, if I count it correctly
Correcting my overlooking: FACES? : FACES-OF = 5:9

Not the topic, but this function does a strange control.

Steeve

In the code, why does it need to check if the contained gobs have 
a consistent data/face/gob ?
It should be consistent at first, no ?
