-.. function:: stack_effect(opcode, [oparg])

    Compute the stack effect of *opcode* with argument *oparg*.
 
+   If the code has a jump target and *jump* is ``True``, :func:`~stack_effect`
+   will return the stack effect of jumping.  If *jump* is ``False``,
+   it will return the stack effect of not jumping. And if *jump* is
+   ``None`` (default), it will return the maximal stack effect of both cases.
