This module provides low-level helper functionality during step imports.

.. warn:: Do not use directly

    It should not be used directly except in behave Runner classes
    that need to provide the correct context (step_registry, matchers, etc.)
    instead of using the global module specific variables.

    during step imports by using fake modules (instead of using module-globals).

    This allows that multiple runners can be used without polluting the
    global variables in problematic modules
    (:mod:`behave.step_registry`, mod:`behave.matchers`).
