Not really...   'for' is a statement, not a function.  If that were the
case 'if ...' and 'print ...' and so on, should also require parens... '

Alternatively... 'for' takes a list as its third (or second) argument, qw//
provides that.  Parens is only syntactic sugar for generating a list. For
example (arguably) this should also work, but the parsing would be almost
impossible:

for keys %hash { print $_ }



My $0.02 -> the core developers should be making Perl faster (and fixing
bugs), as highlighted by the recent comparison on this mailing list.  I
know that in the past, I have moved code to a different language for a
speed increase, once the business rules had stabilized.

Cheers,
Mathew Robertson
