I had a problem similar to that of the recent shape question,
a=. i. 3 4 5
to reshape to rank-2 array with trailing shape unchanged that is shape 12 5,
This works but difficult to remember

this can also work and easier to remember but Henry Rich said recently
that ]\ doesn't support virtual block yet.

Any suggestions of other ways to do it?
