OK, not yet applied because I'm waiting for the other patch, and I'll point out that "for" and "foreach" are the same token as far as perl 5's lexer and parser are concerned. Perhaps just say that "foreach" is accepted as an alias for "for", and keep "for" as the main form. Just to prepare the path for perl 6 :) > --- perlsyn.pod.old Mon Jun 20 08:42:00 2005 > +++ perlsyn.pod Mon Jun 20 08:43:53 2005 > @@ -200,6 +200,9 @@ > LABEL while (EXPR) BLOCK > LABEL while (EXPR) BLOCK continue BLOCK > LABEL for (EXPR; EXPR; EXPR) BLOCK > + LABEL for VAR (LIST) BLOCK > + LABEL for VAR (LIST) BLOCK continue BLOCK > + LABEL foreach (EXPR; EXPR; EXPR) BLOCK > LABEL foreach VAR (LIST) BLOCK > LABEL foreach VAR (LIST) BLOCK continue BLOCK > LABEL BLOCK continue BLOCK >
