I'm not trying to be negative in any way, because this is awesome. I really believe there are so many ways to interact with machines that we haven't figured out yet.

But ... can't you achieve this level of efficiency, maybe even better with a combination of auto completion and snippets?

With python and vim, I use jedi-vim[0] and neosnippet[1] for textmate compatible snippet completion.
