I find it quite intriguing to introduce "language-native" matrices and 2d blocks (which I still find difficult to wrap my head around.)

The reason why most people would more intuitively consider a music score as multidimensional has to do with parallelism or concurrency.

In theory, nothing is stopping you from creating a hyperarray language a la BQN++ (or dare I say QRP). Maybe I glossed over an example, but having proper pointwise application to hyperscalars feels like a must-have.

Second idea is to introduce process parallelism, which could actually make this form of syntax into an execution graph of sorts--could be quite promising!
