"Computational" code that isn't by the vernacular definition of "functional"--and you can write functional code regardless of programming language--is something of a red flag to me. Operate only on your inputs. Return all of your outputs. No side effects.

I think OP meant that functional code is inherently imperative under the hood.

  Sure, but "functional" code, in the vernacular, means a rather less specific version of that. You can, after all, write "functional C". (It can be hard, though.)
