Hello Marten, I was suggesting not changing the shape at all, since dot/matmul/solve do the right thing already in such a case.
In my proposal, only for ndim >=2 do we switch the last two dimensions. Ilhan is right that adding a special case for ndim=1 (error) adds programmer overhead, which is against the general philosophy of NumPy I feel.

I.e., it should still change from what it is now - which is to leave the shape at `(n,)`. Your argument about `dot` and `matmul` having similar behaviour certainly adds weight (but then, as I wrote before, my opinion on this changes by the second, so I'm very happy to defer to others who have a clearer sense of what is the right thing to do here!). I think my main worry now is how to get to be able to use a new state without having to wait 4..6 releases... All the best, Marten
