That doesn't work in some cases - consider a function that returns an
object that the caller must destruct. Or even just returns a struct -
the caller passes in a hidden pointer to where the return type gets
written.
Implicit conversion of function pointers and delegates requires binary
ABI compatibility.
The compiler could insert a thunk that discards the result if the two
delegate types are not ABI compatible.
