I use ```syntastic``` with ```flake8``` nowadays to check PEP8 compliance. I also started using ```riv.vim``` for dealing with RST in vim, this automatically highlights any python source code (when using ```.. code:: python```) using the builtin python syntax file. Do you know of any way, I could check the code snippets in the sphinx sources automatically? Like the way we already run doctest over them (occasionally). Ideally of course, I want to run ```syntastic``` on the sphinx code sections via ```riv.vim```, but I doubt we are that far yet.
