"""
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.

!!! info "Internal use only"
    Things inside this module are not for use outside of RDFLib
    and this module is not part the the RDFLib public API.
