I forgot a biggie: with opDispatch you must know the return type at compile time. You could make the return type be Variant or something, but then that makes it quite different from a "regular" function. Whereas in a dynamic language like Javascript a dynamic method looks just like a regular method (because they're all dynamic, of course).
The Javascript implementations use variants for all variables, values, and function returns. So it isn't any different from defining opDispatch to take and return Variant's.
std.variant needs to be extended with opDispatch so it can execute a call operation on a Variant, then it will be very very similar to Javascript.
