I think allowing this in general is a bad idea - the opDispatch should
only be implemented on a small number of classes.
The reason is simple: a typo in a method name should be a compile time error
the vast majority of the time.
If opDispatch was implemented all over the place, allowing random runtime
extensions, the error is put off until runtime.
Using opDispatch is up to the discretion of the class designer. I doubt
it would be used in any but a small minority of classes.
