elem
import { elem } from "https://github.gh-proxy.cn/raw.githubusercontent.com/baetheus/fun/main/set.ts";Given an insuance of Comparable create a function that takes a value A and returns a predicate over ReadonlySet the returns true if there are any members of the set that are equal to the value.
@example
import * as S from "./set.ts";
import * as N from "./number.ts";
import { pipe } from "./fn.ts";
const elem = S.elem(N.ComparableNumber);
const set = S.set(1, 2, 3);
const result1 = pipe(set, elem(1)); // true
const result2 = pipe(set, elem(10)); // false
