: And can I overload based on return types?
In the case of an MMD tie, the default routine could use the return
type context to break the tie. That's about the limit of what's
practical, I suspect. Possibly we could give some declarative support
to such tiebreaking, but hey, it's like one switch statement max:
given want {
when GoodNum {...}
when EvilNum {...}
when MyNum {...}
when YourNum {...}
when Num {...}
when int {...}
when void {...}
}
On the other hand, in a language like Perl, it's easy to come up
with contexts that don't specify the type context as well as the user
might expect. Plus asking for your return context is not necessarily
going to be terribly efficient anyway if it has to chase up some stack
somewhere looking for the caller, so it's not a programming style we
particularly want to encourage anyway.
