------------------------------------------
It's possible that the `foo.py` file somehow got removed, while
leaving the cached pyc file still on the file system. If the
`__pycache__/foo.pyc` file exists, but the `foo.py` file used to
create it does not, Python will raise an `ImportError` when asked to
import foo. In other words, by default, Python will not support

importing a module unless the source file exists.
Python users who want to deploy sourceless imports are instructed to
create a custom importer that supports this behavior. Options include
importing pycs from a zip file, or locating pyc files where the py
