I have seen it, yes. I'm impressed by the ambition, though I think that in the long term it's better to work with the grain of the platform by extending the web's existing languages rather than creating a new one. Memoization certainly makes Imba a lot faster than VDOM-based frameworks. Of course, it's only really beneficial when not many things have changed!
