The function service.call() is not generated in pyscript_builtins.py.
This likely conflicts with the @service decorator, so I'm not sure how it would be handled.
There are some cases where I need to use service.call() instead of calling the service directly with domain.name(). For instance, I can't call light.turn_on() with transition set to a float because it expects an int, so I need to use service.call() instead.
