Feature idea access to specific overloads

[Thrameos]

Currently we have dispatches that check all overloads. We have added a cache so that overloads are looked up more quickly. But another option to improve performance would be to allow a user to pick a specific overload.

Example.

   cls=JClass("MyClass")
   m=cls.method.overload(JInt, JInt[:]) # Pick the overload (int, int[])
   obj = cls()
   m(obj, 1, [1,2,3])

This would requires some rearrangement so that a dispatch could use types only for resolution. Does this sound like a feature that would get used?
