[Message part 1 (text/plain, inline)]

With the introduction of the fat arrow (=>) function notation in
ECMAScript 6, why not make them prettier by default when
prettify-symbols-mode is turned on?

I propose the following patch, which also adds pretty versions of >=
and <= while we're at it:

BTW, Dmitry, maybe you can also apply it to js2-mode.

The patch looks fine to me, but I have no idea if Eli meant to add the 
cookie at the bottom, or whether that request really makes sense at all.

So I'd prefer if he replies as well.

> BTW, Dmitry, maybe you can also apply it to js2-mode.

No need: it inherits from js-mode already.

I have no preferences in this regard.

> or whether that request really makes sense at all.

In general, ELisp files don't have to have these cookies, but I'd
prefer such changes to trigger adding them, if only for educational
purposes, so our contributors are aware of this subtle issue.

The patch is fine with me.

I'd prefer there not to be any subtle issues here, or that, at least, 
most contributors wouldn't have to be aware of them.

Do we have a clear statement of the problem (and a bug number, maybe)? 
Is it new? Is it likely to be unsolved until the upcoming release?

I just added a few recommendations to CONTRIBUTE about that.

Other than that, we don't have a bug number.  I don't think it's a
bug, more like inconvenient feature: Emacs cannot determine the
encoding of arbitrary text with 100% reliability, so files whose
encoding is not unequivocally determined by their file-name extension
or some other meta-data need a coding cookie to avoid incorrect
decoding.  With UTF-8 encoded files (which is the encoding we prefer
in Emacs), the problem happens in locales whose codeset is not UTF-8,
because Emacs prefers the locale's encoding when no other information
is available.

> Is it new?

No, it's very old.

> Is it likely to be unsolved until the upcoming release?

I'm not aware of anyone working on that, nd it's a large and
complicated problem, so the answer is probably yes.

Thank you, but as long as that's true:

"As of Emacs 24.4, it is no longer necessary to have
explicit 'coding' cookies in *.el files if they are encoded in UTF-8,
but other files need them even if encoded in UTF-8.  And even for *.el
files, having an explicit encoding specification facilitates correct
display of non-ASCII characters when the file is visited in older
Emacs versions."

...we really shouldn't bother contributors with that detail, not should 
we annotate code Elisp files with explicit cookies. Use UTF-8 in them, 
it works fine in Emacs 24.4+, end of story.

If anyone's working on Emacs master using 24.3 or earlier, I'm sure 
there are other footguns they can encounter as well.

I don't see that as a bother, just as useful information that can do
no harm.

I'd have been happy not be have been imparted this "information". 
Especially in the form it was presented: adding those cookies everywhere 
conflicts with that bit of knowledge I've had in my head that since some 
recent Emacs version having UTF-8 in Elisp files is not a problem.

We shouldn't treat them like that just because this problem occurs in 
other files. Nor bring it up in discussions on submitted patches.

There are other ways to raise awareness. Like CONTRIBUTE, which now 
features that information. Most contributors aren't going to touch 
anything but Elisp, ever.

Then please ignore it.  No harm done.

That's a misrepresentation of what the text says.  It explicitly does
NOT require cookies in ELisp files that are encoded in UTF-8.

With all due respect, I will bring up whatever issues I think are
important when discussing patches.  Please feel free to bring up those
that you feel to be important.

I did both.  Where's the harm?

Right (so I'd only change CONTRIBUTE to say that one needn't bother with 
cookies in *.el files, except in those that are also distributed 
separately).

What I'm referring to is requests such as this one, which I believe 
was/is misleading:

http://debbugs.gnu.org/cgi/bugreport.cgi?bug=21568#8

Let's not add that to the general practice.

But there was no issue with that patch. js-mode is not distributed 
separately from Emacs.

No, please leave that text alone.  It's okay the way it is.

I disagree that it was misleading.

Now that we have that text in CONTRIBUTE, that's all there is to say.

I explained my reasons right there and then.

I really don't understand what this attack on me is about.

I feel that the last sentence causes unnecessary doubt on the part of 
the reader. After all, CONTRIBUTE is intended as a guideline for 
developing Emacs, and the less ambiguous it is, the better.

It implied that without that cookie, something in that code might not 
work well.

All right, thank you.

> I explained my reasons right there and then.

As a counterpoint, I don't believe educational purpose is a good enough 
cause to ask people to use coding cookies in UTF-8 encoded Elisp files.

Even for external packages, over time, Emacs versions where they're 
necessary will sail off into distant past. No need to add to the baggage 
the future people will have to deal with.

> I really don't understand what this attack on me is about.

Please excuse any offense, but I'm not calling you names, or anything 
like that.

I see an attempt to bring in extraneous practice into writing Elisp 
files (as well as reviewing the patches), and speak against it.

I see no ambiguity there.  There are requirements, and there's "a good
idea" with an explanation that is left to the contributors to consider
and decide.  I see nothing wrong with leaving the decision with them.

Then I'm sorry that my wording made such interpretation possible.  It
was certainly not intended.

Let's agree to disagree about that, okay?

I cannot see how a dozen-character string most users will never even
notice could possibly be a "baggage" of any significance.

The form and the intense of the objections are out of proportions,
for such an insignificant issue/disagreement.
