The idea is that the norm __call__ method should return a scalar when given a scalar input, or an array when given a sequence input. It is easiest to do the calculation with masked arrays or ndarrays, however, so inputs are converted, keeping track of whether it is a scalar or not, so that if it is a scalar, the output can be converted from 1-element array back to a scalar.
