 * A clear value means:

 * - non-empty string
 * - non-zero number
 * - non-empty array
 * - non-empty object (not array!)
 * - boolean `true`
 *
 * Values like `false`, `0`, empty strings, empty arrays,

 *
 * @example
 * isClearValue("hello") // true
 * isClearValue("") // false
 *
 * @example
 * isClearValue(5) // true
 * isClearValue(0) // false
 *
 * @example
 * isClearValue([1]) // true
 * isClearValue([]) // false
 *
 * @example
 * isClearValue({ a: 1 }) // true
