builtin array union intersection function

[Peng Yu]

There is some code fragment that can take union and intersection of
two arrays.

http://www.perlmonks.org/?node_id=64798

But I'm looking for some functions in the library. Could somebody let
me know if such things are available in the perl library?

What happened when you checked the FAQ for intersection?

perldoc -q intersection

What happened when you checked CPAN for array and intersection?
