This is a different discussion, right? It would be nice to have an order
flag for the core dimensions. The gufunc itself should not care at all
about the outer ones.
All the orders for the core dimensions would be nice probably, including
no contiguity being enforced (or actually, maybe we can define 'K' to
mean that in this context). To be honest, if 'K' means that, it seems
like a decent default.
