Z←L⍴R returns an array of shape L whose items are taken from R in row major order, repeated as necessary.
L is a scalar or vector of non-negative integers, and R is an arbitrary array.
If the right argument is empty, the result consists of ×/⍴L copies of the fill item of R.


For example, in origin-1

      2 3⍴⍳6
 1 2 3
 4 5 6
      2 3⍴⍳0
 0 0 0
 0 0 0

The idea for the latter enhancement was taken from Dyalog APL.
