TypeError: 'module' object is not callable when running with --systemd

[takase1121]

What happened?

Running yin_yang --systemd throws a TypeError: 'module' object is not callable error.
Apparently this is because the --systemd code path does not call sys.exit(), which means the module finishes loading and pip's wrapper attempts to call __main__(), which is a module and thus not callable.

For reference, this is the wrapper executable generated by pip on my system.

#!/usr/bin/python
# -*- coding: utf-8 -*-
import re
import sys
from yin_yang import __main__
if __name__ == "__main__":
    sys.argv[0] = re.sub(r"(-script\.pyw|\.exe)?$", "", sys.argv[0])
    sys.exit(__main__())

yin_yang.__main__ is not callable since it is a module, not a function.
This also affects the -t switch.

Yin-Yang/yin_yang/__main__.py

Line 88 in d6b9c4f

theme_switcher.set_mode(not config.dark_mode)

Yin-Yang/yin_yang/__main__.py

Line 91 in d6b9c4f

theme_switcher.set_desired_theme()

Does not happen on the main (GUI) code path because it calls sys.exit():

Yin-Yang/yin_yang/__main__.py

Line 159 in d6b9c4f

sys.exit(app.exec())
