Inject itself into sys.modules for other PyQt versions

Scenario:

In my app, I from qtpy.QtCore import Qt. I run my app with QT_API=pyqt5, so PyQt5 is preferred, defaulting to PyQt4 if the former is not available. Anyway, PyQt5 is available and my app runs fine.

In some obscure module, or in a stand-alone add-on for my app, I rely on a third-party Python package that imports and works with PyQt4. The import fails. My app breaks.

Use case:

I would like like qtpy to inject itself into sys.modules so that any requests for objects from PyQt4 are resolved, best effort, from qtpy.

You mean optional in a way such that qtpy library users can decide if they want to enable it, like:

# Somewhere at the beginning of an app
# and before any other PyQt loaded ...
import qtpy
qtpy.enable_compatibility()  # for lack of a better name

Will be happy to!
