Identifiers are usually of the form
identifier: idfirst idcont*
For example, identifiers can usually contain digits, but not in the first position.
It sounds like Perl6 will allow
identifier: idfirst idcont* ( [-'] idfirst idcont* )*
What is it and is it current?
Actually, identifiers aren't well defined in Perl5. Tom Christiansen tried to hammer down the definition on p5p in the last two weeks, but I didn't follow the conversation. I'll locate it if you ask.
