Exploring whether the reasoning is adequate is not the same
as refusing to listen. I do not presume my view is correct.

Put slightly differently:
given the surprising passion of the attacks at the
suggestion that perhaps iteration over a matrix might more
consistently yield arrays, I presumed there must be *many*
instances in which it was obviously desirable that such
iteration should yield matrices. So I asked to see some.
In the context of this discussion, I found the (lack of)
responses very interesting. Even in your thoughtful
response it proved irrelevant rather than important for
iteration over matrices to yield matrices.
I understand that some people claim that a general principle
of consistency is involved. I have not been able to
understand this particular design decision as a matter of
consistency, and I have tried to say why. However I am just
a user (and supporter) of numpy, and as indicated in other
posts, I make no pretense of deep insight into the design
decisions. In this case, I simply wanted to open
a discussion of a design decision, not win an "argument".
Anyway, I understand that I am being perceived as
bull-headed here, so I'll let this go. Thanks for your
attempt to help me see the virtues of the current design.
