Cons
Con Lack of Lua examples
Although Howl can be extended in both Lua and MoonScript, almost all bundles are written in MoonScript. This means that it is a bit harder to find examples if you'd rather write your bundle in Lua. MoonScript can be compiled to Lua but the code won't be as clean and understandable as if it would've been written in Lua by hand.
Con CLI only
Pyvim runs through the terminal only.
