Some Perl
To see if @a is a subset of @b in Perl, use this:
all(@a) == any(@b)
(all and any are exported from Quantum::Superposition)
I think it's brilliant that that it's very different from
any(@b) == all(@a)
Which will be true only if all elements in @a are the same as anyone one element in @b. Quantum::Superposition is so brilliant but should really be renamed or aliased to some shorter name. Or can just be a part of "feature" pragma.
