fnamespaces would be part of the frame, replacing fbuiltins, fglobals and flocals. The indirection of an external object hurts performance, so it would have to be a struct within the frame. The aim is clarity; locals, globals and builtins form a trio, so should be implemented as such.

How does replacing three fields with a struct containing three fields reduce the size of the frame or the overhead in creating it?
