What if the author of the code I'm reading didn't respect PEP-8? I don't
think it's fair to invoke PEP-8 as a counter-measure to obviate a syntax
which can clearly be mistaken with something else simply by omitting 2
spaces. Not to mention that I don't see why anyone would want to declare a
variable in there in the first place.
