New submission from Wolfgang Richter:

My understanding of `sys.meta_path` is that it is supposed to allow customized loading of Python modules and packages.

In fact the `importlib` machinery appears to have support for identifying packages with `__init__` files with non-standard suffixes:



However, I find that when I `import wolftest` inside a folder with structure:


None of my sys.meta_path finders are called at all, and instead a namespace is returned.

I was wondering why the `import` statement appears to short-circuit and not check with `sys.meta_path` handlers in this case?
