import * as SG from "./semigroup.ts";
import * as S from "./string.ts";
import { pipe } from "./fn.ts";

const { concat: toList } = pipe(
  S.SemigroupString,
  SG.intercalcate(", "),
);

const list = pipe(
  "apples",
  toList("oranges"),
  toList("and bananas"),
); // list === "apples, oranges, and bananas"
