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

[Anthony Ramine]

Also MODIFIER LETTER COLON (U+A789) is in category Sk (Symbol, Modifier)
and both RATIO (U+2236) and HEBREW PUNCTUATION SOF PASUQ (U+05C3) are in
Po (Punctuation, Other).

None of these categories are included in the categories of Richard's EEP,
thus the compiler would fail with a syntax error, giving the exact location
of the "wrong colon" character.

Now, there is at least three characters that look very similar: U+A789, U+2236, U+05C3. Now you can produce a code that will confuse the hell out of you. Which colon is the right colon?
