(Hmm, now that I think about it, the edge cases are when the strides are 0 or negative. 0-stride axes can simply be removed, and I think we should be able to work back to a first item and flip the sign on the negative strides. The typical positive-stride solution can be found in an open source C++ global array code, IIRC. Double-hmmm...)

Except that it's still NP-complete.
