This includes: * Better ways of checking empty lists * Not shadowing builtin functions like filter * Preventing invalid slash warnings by marking strings as regexps * Removing unnecessary brackets * Lowercase variable names * Adding/updating parameters in docstrings * Removing unused code (lines not chunks) * Change in not a member tests * Changing some methods to static * Shorting range membership checks * Missing parameters * Make some exception handlers more specific * Don't define a lambda to a variable * A few more instance checks to help type checkers
