Looking a bit more, I wonder if the view2D-functionality fits within a 
Cython version of the pxd (it is, and needs to be by its nature, a bit 
hackish).

Perhaps it could be reintroduced later as a wrapper class or subclass of 
array.array.

Another possibility long-term would be somehow adding a "view with a 
different shape"-functionality to Cython itself. Perhaps incorporated in

http://wiki.cython.org/enhancements/buffersyntax

somehow -- perhaps

cdef int[:] arr1d = contigarray(10)
cdef int[:,:] arr2d = <int[0:5,0:2]>arr1d # ok since 5*2==10
