Edifice: Declarative GUI Framework for Python and Qt (github.com)

That's very cool. But QML is so great and easy, I don't see why I should use this, except if I'm insisting on programming with Python. But then, I must remind myself that much of QML code is compiled to C++ these days[1], so there must be some big performance difference between the two?

Anyway, that's still very cool.
