Returns the union of all of its arguments. This creates a new Set that contains all the elements its arguments contain if none of the arguments are a Bag, BagHash, Mix or MixHash.

say <a b d>  bag(<a a b c>); # OUTPUT: «Bag(a(2), b, c, d)␤» 

If any of the arguments are Baggy or Mixy>, the result is a new Bag (or Mix) containing all the elements, each weighted by the highest weight that appeared for that element.

say <a b d>  bag(<a a b c>); # OUTPUT: «Bag(a(2), b, c, d)␤»
