So, I would like to ask you what exception type do you suggest could be suitable to throw in this case?
Interestingly, I looked at the std::exception classes as well when I saw your earlier post and, I agree, there is nothing that leaps out as directly appropriate.
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 Marco
