/**
 * Parses and compiles a formula to a highly optimized function.
 * Combination of `parse` and `compile`.
 *
 * If the formula doesn't match any elements,
 * it returns [`boolbase`](https://github.com/fb55/boolbase)'s `falseFunc`.
 * Otherwise, a function accepting an _index_ is returned, which returns
 * whether or not the passed _index_ matches the formula.
 *
 * Note: The nth-rule starts counting at `1`, the returned function at `0`.
 *
 * @param formula The formula to compile.
 * @example
 * const check = nthCheck("2n+3");
 *
 * check(0); // `false`
 * check(1); // `false`
 * check(2); // `true`
 * check(3); // `false`
 * check(4); // `true`
 * check(5); // `false`
 * check(6); // `true`
