Thank you!

METH_O methods only take a single argument. It does not look like
it constructs any tuples to make the call so it should be as fast
as METH_FASTCALL without being only available for unlimited API
in Python 3.9.

Benchmarks did not reveal any significant impact.

Calls `Ping` D-Bus method on the daemon in sequence.

The github URL has changed but it was not updated at least in some
places, so update it now.

Thank you!

The lint tools are continuously updated which means new errors could
be found. Check for new errors every week.

The `add_exception_mapping` should take the exception type as
an argument not initialized exception.

Apparently there is confusion between `MethodType` and `FunctionType`
in the older versions of mypy. Add an ignore comment to have it be
compatible between mypy versions.

Iterating the MRO in the reversed order will allow to add interfaces to
the given object in a well-defined way - always starting from the base
class. Such ordering will be compatible with adding interfaces manually
one by one.

Thank you!
