This feels like the most important issue to me. It's misleading in
that it suggests that 'rmdir', for example, comes from the 'os'
module. Even after you realize it was injected, it's hard to figure
out where it actually came from since you can't easily tell which
'require' statement introduced it.

Other than that, you could easily have collisions with other libraries
which also inject similar functions. In this respect using a module
name such as 'stringx' is just as bad, since other people are likely
to use it too.
