Submodules need to do linear algebra to compute a basis from the generating
set, as well as to pullback vectors into the subspace. The best way that I
know of to do linear algebra is to write everything in terms of matrices,
and so you need an ordering of your indices. Before, this feature of

Thanks! I've posted a bit more info on the tracker there. It's

It is a very interesting memory management problem.
Wish I could find the bottom of it.
