re: [Jprogramming] v0`v1`v2}y for monads v0,v1,v2

[david alis]

a little experimentation clarifies how monadic amend } works:
   0  } i.10
0
   (,0) } i.8
|rank error
|       (,0)}i.8
   0 1}i.2 4
|length error
|       0 1}i.2 4
    0 1 2 1}i.2 4
|index error
|       0 1 2 1}i.2 4
    0 1 0 1}i.2 4
0 5 2 7

but try for yourself.
