More functions from set theory to manipulate arrays

When programming in perl we need really often to calculate union, intersection, difference between arrays. It will be cool if such functions could be part of the perl6 language.
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
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);
Don't know what to put here.
