f_namespaces would be part of the frame, replacing f_builtins, f_globals

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?
It doesn't.
I think it would improve clarity, but I doubt it is worth the effort.
The point I really wanted to make is that many of the fields in the
frame object belong elsewhere and adding new fields to the frame object
is generally a bad idea.
Cheers,
Mark.
