The main functions are ``is_builtin_valid_args``, ``is_builtin_partial_args``, and ``has_unknown_args``. Other functions in this module support these three. Notably, we create a ``signatures`` registry to enable introspection of builtin functions in any Python version. This includes builtins that have more than one valid signature. Currently, the registry includes builtins from ``builtins``, ``functools``, ``itertools``, and ``operator`` modules. More can be added as requested. We don't guarantee full coverage. Everything in this module should be regarded as implementation details. Users should try to not use this module directly.
