@Paul Moor, I agree with you. Personally, I'd rather not use it, and if it
was used in an importable module I'd claim it was bad practice.
But in general I don't think there is a right answer of if you *should *or
not. I think it is valid for personal preferences to vary here. If this is
something someone forgets to do a lot (and everyone has their own personal
quirks about what's hard/easy for them to remember), then it could be
annoying to the point where this feature could really help them.
But yes, in most cases I'd rather not use it, and I would get peeved if
someone's code they advertised as reusable used this (but then again I also
get peeved when people execute print statements at import time).
