Well, Einstein summation is good, but it only does multiplication and sums. (Or, more generally, some scalar operation and some scalar reduction.) I want a notation that works for ANY type of operation, including non-scalar ones, and that’s what DumPy does. So I’d argue it moves further than Einstein summation.
Along the same vein, could we just move entirely to Einstein summation? It seems like your solution is 90% there.
I assume there is a good reason why you didn’t

I knew there was a reason lol
