Ah in this case, we need to look if we can infer the "shape" of the
matrix from the AST and then tag the said expression with the proper
shape policy. IIRC I have a diag(n) that returns a diagonal matrix with
element from the vector n and it was shaped properly. So the engien is
here (shaped expression) but we need to be sure at CT that the said
matrix has a given property.

I was half-joking , mind you ;)
