Suppose C is rank 3.  What would the following mean:

    C[0<=stride(1)<3][3][all]

I would guess that it would be a rank 2 subarray since a scalar was used as
2nd index?  What I uncertain about is when an expression denotes a
"script proxy thing" (see  Jeremy'sMon, 26 Mar 2001 12:40:12 -0500 (EST) post)
or a subarray.  If a proxy, then is scalar index valid? If a subarray, then
does the all apply to the 1st axis (which has length 3) or to the 2nd axis
of the subarray (which used to be the 3ird axis of C)?
