Vim plugin for executing Python's optional static type checker MyPy

def example(n: int) -> str:
    print(type(n))
    return 'hello'

example("a")  # << incorrect, we've passed a String and not an Integer 

To trigger the plugin, execute either :Mypy or the mapping <Leader>mp

git clone https://github.com/integralist/vim-mypy ~/.vim/bundle/vim-mypy

Plugin 'integralist/vim-mypy'

It seems both Syntastic and Neomake include support for MyPy.
