Other times, I'll just want to let it run. So I have a section of code which, generally, looks like this:

This is the equivalent of
def _pass(*args):
return None
(functions with no explicit return statement implicitly return None)
> def long_running_process(arg1, arg2, arg_etc, report = _pass):

So this is a call to a function that just returns a None, which is
dropped by the interpreter...
