Of course. *We* do. The compiler shouldn't. It should shut up and 
compile, not comment on my coding style. That's what PyLint is for.

I reject the position that the compiler should be guessing what I 
intended. The compiler should do what I say, exactly as I say it, and 
not editorialise with spurious warnings about things which aren't 
errors. Again, that's what PyLint is for.
