Re^5: Syntax Highlighting Editors Beware

Hopefully people coming from Perl 5 will be using syntax-highlighting editors, so they will be able to see at a glance what is and isn't an identifier. :)

As for languages that allow dashes in identifiers, what about LISP, Scheme, etc? And languages like ML allow single quotes in identifiers (without even the requirement that they be followed by a letter).

It's ages since I've seen LISP for the last time, in any case LISP is (syntacticaly) different enough than anything else (I consider Scheme a dialect of LISP) that people would not expect the same (or even just similar) rules for identifiers in LISP and in a syntacticaly rich langauge with loads of infix operators. As far as ML is considered ... I thought it only allows ' at the start of type variables in things like map:: 'a -> 'b -> ['a] -> ['b], but again it's years since I've seen it for the last time. Besides the singlequote is not as dangrous by far. Especially since it can be used in identifiers in Perl5 as well. Even though it has a special meaning there.
