I'm thinking mostly of stackoverflow, but here's an example I ran into (a
lot of) on a job:

somevar = some_complicated_thing(somevar) if
some_other_complicated_thing(somevar) else somevar

Would it really be so bad to just use an if statement?  Why are we
assigning somevar to itself?  This sort of thing was strewn across 3 or 4
physical lines at a time.
