sub signatures without parens?

[Juerd]

for, while, given, loop, etcetera can all be used without parens. Are
the parens around the parameter specification still required? If so,
why? In other languages it may make sense because parens are required
when calling functions too, but in Perl, they're not.

sub foo $foo, [EMAIL PROTECTED] {
    ...
}

You may find this ugly. I do think it's ugly, but wonder if it's
allowed.
