Re: [Numpy-discussion] Index array confusion...

What I'm saying is that in the future it will work correctly. :)
OK :)
Most likely as you suggest, but I haven't really looked at the code, just the rather sickening results.
Well, what I was asking about was really what you meant by "correct". My interpretation of "correct" here was that only tuples and slices would be allowed as indexes. BTW: I found something else that I think is rather odd:
x = [0, 0, 0] y = [1, 1, 1] p = 1 x[p:], y[p:] = y[p:], x[p:] x, y ([0, 1, 1], [1, 0, 0]) x = array([0, 0, 0]) y = array([1, 1, 1]) x[p:], y[p:] = y[p:], x[p:] x, y (array([0, 1, 1]), array([1, 1, 1]))
This seems like a bug to me. The assignment ought to swap the tails of the sequences, as is the case with lists, but with numeric arrays, some weird form of overwriting occurs. I guess this may be an optimization (i.e. to avoid making copies), but it is rather confusing. What do you think?
