In my questions I've just put the locals at the outermost level. I can't
recall if it was expressly forbidden to have locals for subquestions.

Other flags certainly work ... in fact the forbid> flag isn't allowed
at the outer level.

Anyway, attached is a simple differentiation of composite functions
