Opposition to Python type hints

I never type an existing variable or function name directly in python source; I always use ctrl-p/ctrl-n in vim to autocomplete it. I load the other file containing the original name in a new tab if I have to, just so autocomplete can match on it. That and pyflakes help a lot. It also helps to use _lengthy_ function and variable names that are unique. However, refactoring modules and functions in a large codebase is still agony.
