/**
 * ## `within` : 创建一个检查数值是否在指定范围内的函数
 * - 返回一个函数，用于判断给定值是否在 `[start, end) `闭区间范围内
 * @example
 * ```ts
 * const is_in_range = within(0, 100)
 * console.log(is_in_range(50))  // true
 * console.log(is_in_range(-1))  // false
 * console.log(is_in_range(101)) // false
 * console.log(is_in_range(100) // false
 * console.log(within(Range(0, 100))(50)) // true
 * ```
 * @example
 * ```ts
 *const validateCelsius = pipe(
 *  (f: number) => (f - 32) * 5/9,  // 华氏度转摄氏度
 *  within(-273.15, 100)      // 检查是否在有效的摄氏度范围内
 *)
 *
 *console.log(validateCelsius(32))   // true (0°C)
 *```
