There are a lot of improvements that can practically be incorporated.
While many of these are performance related, there are also improvements in
accuracy over some ranges

arr.names should have been arr.dtype.names in that pack_last_axis function

Apologies, it seems that I skipped to the end of @ahaldane's remark - we're

Why is the list of tuples a useful thing to have in the first place? If the
goal is to convert an array into a structured array, you can do that far
more efficiently with:
def make_tup_dtype(arr):
"""
Attempt to make a type capable of viewing the last axis of an
array, even if it is non-co

I am a firm believer that the current situation is not sustainable. There
are a lot of improvements that can practically be incorporated. While many
of these are performance related, there are also improvements in accuracy
over some ranges of parameters that cannot be incorporated. I also think
