[erlang-questions] EEP 40 - A proposal for Unicode variable and atom names in Erlang.

[Richard O'Keefe]

A Unicode expert has suggested not allowing all of Pc at the
beginning of a variable but just the ASCII and FULLWIDTH
versions of "_".  It's not yet clear to me what should be
done in the body of an identifier; allowing precisely these
characters instead of all of Pc is enough for us to begin
with, and we can add the other Pc characters later.  Expect
yet another revision next week.
