[Numpy-discussion] problem with view() and strided arrays?

Actually -- it seems like view() doesn't work with strided arrays at  
all. (?)

In : a = numpy.ones((4,32), dtype=numpy.uint8)

In : a.view(numpy.uint16).shape
Out: (4, 16)

In : a[:,:16].view(numpy.uint16)
ValueError: new type not compatible with array.

I think this might be a recent regression, because before I updated my  
numpy installation to the latest SVN version (to check if the bug was  
fixed!), I'm pretty sure this kind of operation worked.
