// We seem to have a problem with the automatically generated code for the

// the code to handle both cases, when the switching function that is generated
// is called it is always called with 4 arguments even when there are in fact 3, so
// it fails to find the right function.
//  To work around this, we here construct a python-callable method that does
// not have a variable number of arguments and have it call the original function.
