Re: perl "alternating foreach" feature idea

"Erik 2.0" <erik@xxxxxxx> writes:

in the spirit of both perl's brevity and it's "do what i mean" array
contexts, it would be an appropriate feature for foreach loops to
support an array of variables as the iterator as well as just a
scalar. this would cause perl to alternate across the array:

for example:

foreach ($key, $val) in (@pairs) {
print "$key=$val\n";
}

an odd number of values in @pairs would cause an extra iteration with
$val set to undef

Great idea! When you've implemented it, you should send your patch to p5p
to get it integrated with mainline Perl.
