98// Note that cv-qualification is dropped from
99// the "hidden this" argument of member functions; that is a
100// necessary sacrifice to ensure that an lvalue from_python converter
101// is used. A pointer is not used so that None will be rejected for
102// overload resolution.
103//
104// The second form of get_signature essentially downcasts the "hidden
105// this" argument of member functions to Target, because the function
106// may actually be a member of a base class which is not wrapped, and
107// in that case conversion from python would fail.
