I wrote that wrong. I should have said "array_var" not "array_expr". I am
certainly not advocating quoting expressions, and didn't mean to imply that
here. My point was that if a token is always interpreted as a keyword rather
than an identifier when there is ambiguity, then quoting would let users name an
identifier "each" or "EACH". In any event, I will not push this since it
doesn't address the real issue of language changes not breaking the general case
of legacy code; it only says how users can insulate themselves. -- Darren Duncan
