NAME

Set::Product - generates the cartesian product of a set of lists

SYNOPSIS

use Set::Product qw(product);

product { say "@_" } [1..10], ['A'..'E'], ['u'..'z'];

DESCRIPTION

The Set::Product module generates the cartesian product of a set of lists.

FUNCTIONS

product

product { BLOCK } \@array1, \@array2, ...

Evaluates BLOCK and sets @_ to each tuple in the cartesian product for the list of array references.

NOTES

If Set::Product::XS is installed, this module will automatically use it. You can prevent that and stick with the pure Perl version by setting the SET_PRODUCT_PP or PURE_PERL environment varible before using this module.
