Some L2 tests were asserting that the std::bad_function_call exception should be thrown when a bad callback is called. We will be changing that behavior so that the exception is thrown when the callback connection is established, requiring updated test cases.
The CalleeHandle class is the "owner" of the callback function objects associated with a callback connection. As such, it will check the validity of those function objects and throw the EmptyFunctionObject exception if either the callback or cleanup function is empty / invalid.
