How is it not referentially transparent and how does it use mutable state?

• seanmcdirmid 9y ago
  APL supports reassignment and has state based control flow.

    Most functional languages (ocaml, lisp, etc) support reassignment though.

      Yes, but APL was designed before the rules were written. It doesn’t have the feeling of a FP.

        Aren't you composing a lot of functions and operators?
