Hi Felipe,

I've been missing a testing suite for vim too. One possible solution is
to use the same technique that vim is using itself to test the code.
There are now bunch of assert functions (:h assert_equal(), etc.).

Another thing that would be awesome is to have a PureScript backend
for VimL and develop vim plugins in a strongly typed language. That would
rule out a lot of bugs. There is Python backend for Purescript which
one could use to write plugins that are using vim python interface.

Cheers,
Marcin
