not convinced that it can be used seamlessly without some relatively

I repeat that opDispatch and auto ref were invented for this, so
anything that doesn't work now is a bug. There are no changes needed to
the language, only fix the bugs :o).
How do you call template member functions of the held object without
changing opDispatch?
The idea is to pass the entire template instantiation as the string.
obj.foo!(bar, baz)(a, b);
->
obj.opDispatch!("foo!(bar, baz)")(a, b);

I would have thought that the template parameters would be passed to opDispatch
i.e.
obj.opDispatch!("foo",bar,baz)(a,b);
although I don't know how opDispatch would be written to handle such a call in
a generic manner, i.e. I would want to define it as
obj.opDispatch!(string name, Targs..,Vargs..)(Vargs args) { ... }
but stuff like that isn't possible currently.
That said, parsing the string for "bar" and "baz" is both difficult and doesn't provide access
inside opDispatch to "bar" and "baz".
