How do they make tensors? Would our notation help?

Which document should we share with them? '09 document or P0332? All of them?

From what I can tell of TensorFlow, the Tensor type itself has all run-time dimensions:

It seems like the point is to create big expression trees and reuse them, less so to make (say) 2x2 matrix-matrix multiplication as fast as possible. Something like TensorFlow might want to use something like mdspan inside, if using run-time compilation. (That would make sense for TF's Const.)
