// 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.
