The point of this repository is to illustrate how we can get into "flaky" situations with circular dependencies.

In particular, this illustrates how the removal of a dependency can cause Python to begin complaining about a "new" Circular Dependency

The situation is:

left_package.lower -> right_package.right

while

right_package.right -> left_package.upper

This means that at a package level, there is a circular dependency. But with respect to individual modules, there is not a circular dependency.

This circular dependency is still bad because we do not have control over when __init__.py will run.

I am personally surprised that success.py can actually run without crashing.
