I think that is significant scope creep for the .npy format, and I
would like to avoid it. A case might be made for letting np.savez()
simply pickle non-arrays that it is given. I have a vague recollection
that that was discussed when savez() was designed and rejected as a
moral hazard, but I could be wrong. The .npy and .npz formats are
intentionally limited by design. As soon as you feel constrained by
those limitations, you should start using more full-fledged and
standard file formats.
