numpypy buffer interface for slices different from numpy
Hi group! I stumbled upon a difference in numpypy's ndarray buffer interface. If I take the address of the data of a slice in numpy, I get a pointer to the first element in the slice. In numpypy I get a pointer to the data I took the slice from. I wonder if this is a bug or deliberate? If it's a bug, it's probably merely an omission of adding the offset to the data pointer. Here's what I observed: $ pypy Python 2.7.3 (aa7b56060ddd, Apr 22 2013, 22:03:12) [PyPy 2.0.0-beta2 with GCC 4.4.3] on linux2 Type "help", "copyright", "credits" or "license" for more information. And now for something completely different: ``PyPy 1.2 released - http://pypy.org/''
$ python Python 2.7.3 (default, Apr 10 2013, 05:46:21) [GCC 4.6.3] on linux2 Type "help", "copyright", "credits" or "license" for more information.
