I certainly wasn't expecting something to be available for review now or in
the near future. I was actually mostly thinking about language syntax and
semantics when I started writing that email. I think those are more likely
to be frozen early on in the 3.0 development cycle. I seem to recall some
message(s) on python-dev a long time ago about maybe restricting outside
modification of a module's globals, e.g.:
 import a
 a.x = 1 # proposed as an error?
which would have allowed easier optimization of global access.
