I've packaged a vim plugin that provides live code checking for Python 2 and 3
using pyflakes. Combined with code completion from vim-youcompleteme it makes
vim feel very IDE-like. I often find it pointing out mistakes in my Python
without needing to run the code. vim-khuno is available in testing and
unstable.

I thought this will be of interest to any vim user writing Python.
