    A note about argument marshalling with built-in types.
    There are three distinct cases for member (non-static) methods:

    1) An ordinary member function.  In this case, the first param in
    the param list is 'this'.  For builtin types, 'this' is taken from
    the first argument to the wrapper (usually called 'self); it's not
    extracted from the second argument (which is usually a tuple).

    2) A constructor for a non-director class.  In this case, the
    param list doesn't contain an entry for 'this', but the first ('self')
    argument to the wrapper *does* contain the newly-allocated,
    uninitialized object.

    3) A constructor for a director class.  In this case, the param
    list contains a 'self' param, which comes from the first argument
    to the wrapper function.
