Fun fact: If monadic ⊤ was 2∘⊥⍣¯1 then binary operations would be under a tack; ⍢⊤

@Adám Yes! That's one of the combo delights I remember discovering in J: &.#:. Looks way cooler in APL, though :P

@finooiigee I clearly should.

@B.Wilson that's really interesting thanks

@B.Wilson Nice archeology work! I feel like that should be recorded somewhere for posterity. Not sure how it can be fit into the Dyalog APL page on APL Wiki, though.

@hyper-neutrino Can you give chat.stackexchange.com/users/568808/user52971 access?

@Adám done

thx
