[Cython] Class methods returning C++ class references are not dealt with correctly?

[Bradley M. Froehle]

Hey Yury:

Yes, you are right.  I was thinking this was a function and not a method.
 As an even ickier workaround:

#define TokenStack_top_p(token_stack)  &token_stack->top()

cdef extern from "............":
    Token* TokenStack_top_p(TokenStack*) except +

cdef Token* tok = TokenStack_top_p(self.pEngine.OStack)
