If the stdlib were to use implicit namespace packages
( https://www.python.org/dev/peps/pep-0420/ ) and the various
loaders/importers as well, then python could do what I've done
with an embedded python application for years. Freeze the
stdlib (or put it in a zipfile or whatever is fast). Then
arrange PYTHONPATH to first look on the filesystem and then look
in the frozen/ziped storage.
Presumably that would eliminate the performance advantages of the
frozen/zipped storage because now Python would still have to issue
all the stat calls to first check for the existence of a .py file.
