It may look like just 3, but the question is whether it's depth has
increased (whether it gets nested). My understanding is that under
Sharp APL it would. I don't know what the symbol is under Sharp for
computing depth (or if there even is one), but in some other APLs it's ≡
. I would expect it's depth to be non-0 if it's nested. So assuming ≡
is the symbol for depth, try each of these:
≡3
≡<3
≡<<3
