No, currently it wouldn't know where to look.  And that's a good thing
because AC never should modify anything not inbetween "clinic start
generated code" and "clinic end generated code".

But Larry has said that in the future the wohl PyMethodDef array might
be generated by AC in a separate block (that you have to indicate in
the file as well).
