It *should* throw up a syntax error.  If both letters were valid, it
would silently create a second identifier, and you would have some fun
tracking down the bug.

I say "*should*" because, at the moment, it seems to accept some
additional characters, in at least some environments.  In particular,
using Idle from 2.5.0, I just noticed that I can apparently use at
least some Latin-1 characters.

>>> ó = 5
>>> print ó
5

>>> ¿=7
SyntaxError: invalid syntax
>>> Æ=7
>>> Æ
7

[And no, this doesn't mean "it's already in use; no big deal", because
the Latin-1 characters are not the biggest concern.]
