I think that is pretty cool - literally made me screen "Yes!" when I saw it and I don't do this for your everyday framework.

I think the beauty of keras was the perfect balance between simplicity/abstraction and flexibility. I moved to PyTorch eventually but one thing I always missed was this. And now, to have it leapfrog the current fragmentation and just achieve what seems to be a true multi-backend is pretty awesome.

Looking forward to the next steps!
