Re: array element as foreach iterator

I have to admit - I've never thought about doing this ... but I can see how that would be some really nice-tasting syntactic sugar.... I would normally look at it this way:

#! user/bin/perl
use warnings;
use strict;

my @x = ( [1,1], [2,2], [3,3] );

sub do_something {}

# so, I use this method instead
foreach my $a1 (@x) {
  foreach my $a2 (@x) {
    do_something($a1, $a2);
  }
}

But maybe that's just me thinking "inside the box" again.

Yes, that too was my first thought. But, I actually had 10 nested foreach loops, and the programmer inside said "sounds like an array", so I tried to use elements of an array as the iterators. As always, TMTOWTDI.	[reply]
