This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.
# Set.^ (from ruby core) --- ^(enum) --- Returns a new set containing elements exclusive between the set and the given enumerable object. `(set ^ enum)` is equivalent to `((set | enum) - (set & enum))`. Set[1, 2] ^ Set[2, 3] #=> #<Set: {3, 1}> Set[1, 'b', 'c'] ^ ['b', 'd'] #=> #<Set: {"d", 1, "c"}>
