IMO, the only time I think "if x" is really dangerous is if you are
using "if x" instead of "if x is None" to distinguish between None and
a type that can have false values.
Well, that would be an exceptionally bad way to test for None-ness,
since None is false. The test would never succeed.
Having said that, it would sure be nice to be able to write
if myList is not empty:
instead of
if len(myList) != 0:
I can agree with this.
I'm getting this sneaking suspicion that you guys are all putting us on.
