Thanks for the report, but importlib.import_module() doesn't accept a path of a Python module:

    https://docs.python.org/3/library/importlib.html#importlib.import_module

So, the correct way to use the API is:

    import importlib
    importlib.import_module('poc')

Whether we should explicitly reject passing a file path to import_module() is up to the importlib maintainers.
