Sometimes scala is a bit too clever in its handling of parens and you just have
to add another pair, in this case to disambiguate between these two methods:

def += (kv1 : (A, B), kv2 : (A, B), kvs : (A, B)*) : Unit
  Add two or more key/value pairs to this map.
  (The one you called)
def += (kv : (A, B)) : Unit
  Add a key/value pair to this map.
  (The one you thought you called)
