/**
 * Will try to promisify `fn` with native Promise,

 * different promise module to `relikeValue.promise`, for example `pinkie`.
 *
 * **Example**
 *
 * ```js
 * const fs = require('fs')
 * const request = require('request')
 * const relikeValue = require('relike-all')
 *
 * relikeValue(fs.readFile, 'package.json', 'utf-8').then(data => {
 *   console.log(JSON.parse(data).name)
 * })
 *
 * // handles multiple arguments by default (comes from `request`)
 * relikeValue(request, 'http://www.tunnckocore.tk/').then(result => {
 *   const [httpResponse, body] = result
 * })
 * ```
 *
 * @name   relike-all
 * @param  {Anything} `[args...]` any number of any type from string to function (number, array, boolean, etc)
 * @return {Promise} promise
 * @api public
