Ok, I have stolen boost.function exception:

    struct bad_function_call : std::runtime_error
      bad_function_call() : std::runtime_error("call to empty function") {}

With this I have two things:

- A correct exception to throw when an empty slot is called

- The proof that you are right: it's idiomatic to throw an exception
in this case

I plan to post an update with exception's support (I have already
implemented it in the meantime ;-) just after Easter holidays (Monday
evening), so to leave some time for other suggestions.

Thanks again
