In my view this is clear progress.

Modules do not interfere with each other: module 1 does not change the
environment for module 2 (as happened by mistake in your example),
module 2 does not see locals declared in module 1, etc. Each module is
sintactically distinct, with a clear boundary around each. They are
much more self contained.
