Since it objectively works in u, probably what you mean is that there's an
efficiency case for doing it in v instead, or that Z: can have some surprises
in u. Why not state that?
Just the case from the other way is a bit more annoying to do in v
0 {{y[1 Z:y>10}} F.. + i.10
15
vs.
NB. explicit code to avoid repeating op
0 [ F.. (4 : ('r=.x+y';'1 Z: r>10';'r')) i.10
15
NB. forgot the goal here and repeated op anyway
0 [ F.. (+[1 Z: [: >&10 +) i.10
15
0 [ F.. ([: ([[1 Z: >&10) +) i.10
15
