Suppose you have a class
class A
{
void foo(char);
void foo(long);
};
Now one question: the compiler allows a call like this?
A a;
a.foo(7);
(Hint mine no)
So I would say a _possible_ policy is to not allow to register say
set(f6);
if is already registered a function with a "compatible" signature.
This is both more safe (IMHO) and avoid complications in the API
Just an opinion
