When you have authority over the coding guideline. Naming things is not
something limited to programming and most people know the importance of
choosing the appropriate ones. If on the other hand some names have
been chosen that have actual side effect(in python program), like
builtin function names, it is appropriate to point that out, though I
don't see that case here.
