[Numpy-discussion] Should dtypes have an ndim attribute?

[Gerrit Holl]

Hi,

I have made a modest proposal in issue #6752
<https://github.com/numpy/numpy/issues/6752>.  Basically, the proposal
is to add an `ndim` attribute to dtypes.  Currently, arrays have a
shape and an ndim attribute, where ndim equals len(shape).  dtype
objects have a shape attribute, but no corresponding ndim.

An ndim attribute would help in immediately determining whether a
field in a structured dtype is multidimensional or not.

Thoughts?
