fix: implement-curry-with-placeholder bug

[cool4zbl]

Whether to check nextArgs.length before its shift?
Otherwise, the code below will get a curriedJoin(...)(...) is not a function error.

const join = (a, b, c) => {
  return `${a}_${b}_${c}`
}
const curriedJoin = curry(join)
console.log(curriedJoin(_, _, _)(1)(_, 3)(2)) // '1_2_3'
