Subtract arrays (RE: I have contributed a module to CPAN)

In the works unless I know of something better: a module to return the subtraction of the contents of arrays.

You mean something like:

    # "Subtract" (remove) elements of @minus from @list:
    my %dup;
    @dup{@minus}= ();
    @list= grep { exists $dup{$_} } @list;

Update: Thanks to PrincePawn for noting that I left out "not" above.

Set::Scalar has functionality like this.. Set intersections, unions, subsets, etc.

[princepawn]

This looks like the intersection

grep { not exists $dup{$_} } @list

should be the difference.
