o/, is there a built-in/simpler version for inverse of where? I wrote {1@⍵⊢0⍴⍨⌈/⍵}, but I seem to remember there was an easier way...

@Ven ⍸⍣¯1?
If you know the final mask size, then (⍳size)∊indices
Automatic sizing: ⊢∊⍨∘⍳⌈/
⊢∊⍨∘⍳∘⊃⌈/ for multi-dim arr.

@Adám I tried that, but that didn't work 
⍸⍤¯1⊢1 4
the max size is just the highest here, but that's easily configurable with ⍺←⌈/⍵
So something like ⍳∘(⌈/)∊⊢ / ⊢∊⍨⍳(⌈/)

@Ven uh, ⍣ not ⍤
Did you APLcart it?

@Adám ugh, I guess I typed it wrong both times... Thanks. (and I did, but didn't try inverse)
