Having a simple 1-d array in numpy would be great. In an ideal world
I would rather see a 1-d array implemented in C together with a set of
array operations that is rich enough to allow trivial implementation
of ndarray in pure python.
When you say "does not define the dimensions or strides" do you refer
to python interface or to C struct? I thought python did not allow to
add data members to object structs in subclasses.

If python lets you do it, how will that block of memory know its size?
