It looks like what you want is a zero-stride array that I proposed
some time ago. See "zeros in strides" thread

I've posted a patch to the list, but it was met with a mild opposition
from Travis, so I've never committed it to SVN.    The final word was:

I would also like to get more opinions about Sasha's proposal for
zero-stride arrays.


If you agree that zero-stride array would provide the functionality
that you need, it may tip the ballance towards accepting that patch.
