Have opDispatch look up the string in an associative array that returns
an associated delegate, then call the delegate.
The dynamic part will be loading up the associative array at run time.
This is not exactly what everyone of us expected. I'd like to have
something like
void foo(Object o) {
o.duckMethod();
}
foo(new Object() { void duckMethod() {} });
The feature isn't very dynamic since the dispatch rules are defined
statically. The only thing you can do is rewire the associative array
when forwarding statically precalculated dispatching.
I believe you should distinguish duck types from other types.
You shouldn't be able to call duckMethod given a reference to Object, it's
a statically-typed language, after all.
