Q's combinators are interesting. Especially overloading on arity: f' = map f x f' y = map f (zip x y) x f/: y = map (f x) y x f\: y = map (λ x. f x y) x f/ (unary) = fix λ g. λ y. if f y = y then y else g (f y) f/ (binary) = reduce f x f/ y = fold f x y x f\ y = scan f x y

Using fold instead of for-loop is annoying. But one benefit: flip a character to unroll the state of the fold. q) ((); 0) check/ "()({)" "({" 3 q) ((); 0) check\ "()({)" ,"(" 0 "" 0 ,"(" 0 "({" 0 "({" 3

Wouldn't that be APL?

Yes, Q is a modern APL.

There’s an interesting fork in history between APL → J → K → Q from 60s and SASL → KRC → Miranda → Haskell from 70s.
