First this looks really great, I just tested it.
Before we tried https://github.com/skatejs/val/issues/react-integration, but that was broken.
Then we tried our own, unfortunately with bugs for children.
And yours really works great so far.

Except, it seems I can't use any of these:
https://reactjs.org/docs/events.html

Note: I know about the events object and can get it to work with it.

But I want to use also React's event system
