Algorithm::Loops - Looping constructs:

NestedLoops, MapCar, Filter, and NextPermute

Algorithm::Loops provides several functions for doing different types of looping constructs:

Filter

Similar to C<map> but designed for use with s/// and other reflexive operations. Returns a modified copy of a list.

MapCar, MapCarU, MapCarE, and MapCarMin

All similar to C<map> but loop over multiple lists at the same time.

NextPermute and NextPermuteNum

Efficiently find all (unique) permutations of a list, even if it contains duplicate values.

NestedLoops

Simulate C<foreach> loops nested arbitrarily deep.
