Thanks for the suggestion, this looks interesting and will probably come in handy.

Before I can tackle this, I first need to answer a lot of questions about how best to implement this. I doubt I'll get around breaking changes and rewriting a few things from scratch (that's how poor planning ends), so I'll only tackle this when I have more time.
