[pypy-dev] Before I start hacking on numpy

There are a few things to be done before we start on a
multi-dimensional array. First, we need to do some refactoring to get
all of the 1D parts out of BaseArray and into the SingleDimArray
class. Also, we need to decide if we want to keep single dimensional
arrays as a specialized case or just use the same multi-dimensional
array for everything. We can also consider adding a 2D class as well.
Personally, I think that we should do the refactoring, implement a
multi-dim array while keeping the 1D array for now, and compare the
performance of using the multi-dim array for 1D arrays vs. using the
SingleDimArray class.
