It will be cool if such functions could be part of the perl6 language. =head1 DESCRIPTION Functions from Set theory are often needed when manipulating arrays, I'd like to to find most of them in the new perl6 language. The most usefull and needed are, for me, - union - intersection - difference after we could find some others like : - "unicity" to eliminate duplicated elements =head1 IMPLEMENTATION I'd like to use these functions in this way : @c = union (@a, @b); # wich is different from @c = (@a, @b) because union do not duplicate same elements @c = intersection (@a, @b); @c = diff(@a, @b); =head2 Checkpointing Don't know what to put here. =head2 Event loop =head1 REFERENCES Set Theory
