Here's a basic implementation. docstring + tests not updated yet, also I wonder whether axis should be the first argument, but that could create compatibility problems.
AFAICS, I never received an answer, but IMHO this should be integrated into NumPy. Any objections?
I often work with vectors inside an array, so I would find it useful (even if it is just a two-line wrapper). I'd also add an "out" argument, so that the signature is similar to that of max, min, etc.
norm(a, ord=None, axis=None, out=None)
