in reply to Re: Pair of items
in thread Pair of items

Quantum::Superpositions offers an elegant solution: 
use Quantum::Superpositions;

my $list1 = [1,2,3];
my $list2 = [4,5,6];

print "No common items" if all(@$list1) != all(@$list2);

Basically, if all of the elements in list1 are not equal to all of the elements in list2, that will print "No Common Items"

    And, that is the solution I would propose in Perl6.

    However, Quantum::Superpositions is not a core module nor is it meant to be used in production code. It's a plaything conceived in the bowels of TheDamian's mind that hasn't been thoroughly tested. *shrugs* TMTOWDI

    The idea is a little like C++ templates, except not quite so brain-meltingly complicated. -- TheDamian, Exegesis 6

    Please remember that I'm crufty and crochety. All opinions are purely mine and all code is untested, unless otherwise specified.
