+1. Editor's job, neither CPython's interpreter nor core grammar.

You misunderstood my point. I was referring to identifier, what the
proposal is asking. Of course unicode is availalble, people always argue
about unicode, who wouldn't know Python doesn't support unicode.

Why should I write pi in two English characters instead of typing π? Python
is so popular among the science community, so shouldn't we add that as
well? Excerpt from the question on
http://programmers.stackexchange.com/questions/16010/is-it-bad-to-use-unicode-characters-in-variable-names
:

t = (µw-µl)/c  # those are used in
e = ε/c        # multiple places.
σw_new = (σw**2 * (1 - (σw**2)/(c**2)*Wwin(t, e)) + γ**2)**.5

If we were to vote on popularity, we'd look at comparing the size of
functional programmers vs scientists. Not saying functional programmers
don't matter (already stressed this in my previous comment), but this is
more like an editor plugin. I personally would love to see such in VIM.

Thanks.
