The recent discussion of Matlab's repmat
plus some recent use of grids leads me to ask:
should numpy contain a true repeated array object,
where one single copy of the data supports
a full set of array operations?  (So that,
e.g., repmat(x,(3,2)) would simply point
to the x data or, if desired, make a single
copy of it.)

And actually this seems a special case of
a truly space-saving Kronecker product.

Cheers,
Alan Isaac
