"""
This module contains type aliases that should only be used when type checking
as it would otherwise introduce a runtime dependency on `typing_extensions` for
older python versions which is not desirable.

This was made mainly to accommodate ``sphinx-autodoc-typehints`` which cannot
recognize type aliases from imported files if the type aliases are defined
inside ``if TYPE_CHECKING:``. So instead of placing the type aliases in normal
modules inside ``TYPE_CHECKING`` guards they are in this file which should only
be imported inside ``TYPE_CHECKING`` guards.

.. important::
    Things inside this module are not for use outside of RDFLib
    and this module is not part the the RDFLib public API.
