The current foreach syntax is:
foreach (VAR in ARRAY [ limit EXP ]) STMT
foreach ([VAR1, VAR2, ...] in ARRAY [ limit EXP ]) STMT
I propose making it:
foreach (VAR in ARRAY [ as VALUE ] [ limit EXP ]) STMT
foreach ([VAR1, VAR2, ...] in ARRAY [ as VALUE ] [ limit EXP ]) STMT
This way we can avoid repeated array lookups for the common case that you're
only interested in ARRAY[VAR1,VAR2,...] anyway.

------- Additional Comments From jistone at redhat dot com 2010-04-06 22:16 -------
I hesitate to make "as" a full-blown keyword, as even in the testsuite there are
instances of "as" being a variable. But since this proposed use is fully
contextual, I think it's ok to act like a foreach-only keyword.
