I strongly favor doing it, but with keepshape (or just "keep", to make
it short) and not by default. It's at least as common to take a mean
down an axis of a 2D array and plot it (r

The text is getting kind of broken up so I'm chopping it and starting from
scratch.
To the question of whether it's a good idea to change the default behavior
of mean and friends to not reduce over the chosen axis, I have to agree with
Robert: too much code breakage for to little gain, so

If you're looking for user input ... +1 on having a keepdims capability. I
have myself implemented many such functions with a keepdims=1 keyword. No
real preference on how it's impelemented, though the potential for
breakage is a concern ...

Hi All,
I think it would enhance broadcasting if functions like sum, mean, etc
didn't change the number of dimensions. For example, suppose one wanted to
subtract the mean along dimension 2 from the same axis of the original
array, then something like
In [44]: a = ones((2,3,4,5))
In [45]: a -= a
