Ok, i have narrowed my problem a bit.  PyNumberMethods is being
accessed properly, so i mistitled this thread.  The problem is that
the MyObject_add() method is called only when both operands being
added are the same type.  IOW, MyObject_add() is called only when
adding "MyObject + MyObject" and isnt called when adding "MyObject +
8".  How, using an extension type, can you implement "apples +
oranges"???

Clearly it is beneficial to enforce type safety and only allow "apples
+ apples" but there are other times when it is necessary to have the
flexibility to do "apples + oranges".  For instance, I may want to be
able to add a stock variable with a flow variable in addition to
adding two stock variables.  How can i tweak the addition method for
an extension type to be able to accommodate this?

TIA,
