// This file declares a series of overloaded invoke(...) functions,
// used to invoke wrapped C++ function (object)s from Python. Each one
// accepts:
//
// - a tag which identifies the invocation syntax (e.g. member
// functions must be invoked with a different syntax from regular
// functions)
//
// - a pointer to a result converter type, used solely as a way of
// transmitting the type of the result converter to the function (or
// an int, if the return type is void).
//
// - the "function", which may be a function object, a function or
// member function pointer, or a defaulted_virtual_fn.
//
// - The arg_from_python converters for each of the arguments to be
// passed to the function being invoked.
