How powerful is autocomplete, when statically typed languages also provide it?
Thinks like tern.js[0] or my own Aulx[1] provide that with varying success. Visual Studio's JS autocompletion is also stellar. The techniques used could be applied (with tweaks) to most dynamic languages.

I need to do another video soon, the work has progressed a bit further since then.
