[Numpy-discussion] Re: Add to NumPy a function to compute cumulative sums from 0.

With this I agree, this sounds like a more radical (in a good way) solution.

So I think this is a feature request of "prepend", "append" in a convenient fashion not to ufuncs but to ndarray. Because concatenation is just pain in NumPy and ubiquitous operation all around. Hence probably we should get a decision on that instead of discussing each case separately.
