I get an unexpected result when subtracting a List from a Bag with the set
difference operator (-). Subtracting Bags from Lists or Bags works fine, as
does the baggy addition operator:
say bag(<a b>) (+) bag(<a a>); # Bag(a(3), b)
say bag(<a b>) (+) <a a>; # Bag(a(3), b)
say <a b> (+) bag(<a a>); # Bag(a(3), b)
say bag(<a a a b>) (-) bag(<a a>); # Bag(a, b)
say bag(<a a a b>) (-) <a a>; # Bag(a(2), b) seems wrong
say <a a a b> (-) bag(<a a>); # Bag(a, b)
