Module Version: 1.008
Math::Subsets::List - Generate all the subsets of a list.

use Math::Subsets::List; subsets {say "@_"} qw(a b c); # # a # b # c # a b # a c # b c # a b c

Generate all the subsets of a list and process them using the standard Perl metaphor.

`subsets()`

returns the number of subsets. Please note that this includes the empty set as it is a subset of all sets.

Please note that the order in which the subsets are generated is not guaranteed, so please do not rely on it.

`subsets()`

is easy to use and fast. It is written in 100% Pure Perl.

The `subsets()`

function is exported.

Standard Module::Build process for building and installing modules:

perl Build.PL ./Build ./Build test ./Build install

Or, if you're on a platform (like DOS or Windows) that doesn't require the "./" notation, you can do this:

perl Build.PL Build Build test Build install

With lots of help and advice from Philip Rumpff to who I am most grateful.
