TypeScript 的尴尬：模块不如wepback完善

同一段“导入模块”的代码，截然不同的处理

Bug重现代码：

void function () {
    isSupportedRange('http://static.com/1GB.bin').then(bool => {
        // ...
    });
}();

import * as http from 'http';
import * as https from 'https';
import { URL } from 'url';

function isSupportedRange(url: URL | string): Promise<boolean> {
    // use imported module: http, https, and URL
}

Wepback:

/* harmony import */ var http__WEBPACK_IMPORTED_MODULE_0__ = __webpack_require__(1);
/* harmony import */ var http__WEBPACK_IMPORTED_MODULE_0___default = /*#__PURE__*/__webpack_require__.n(http__WEBPACK_IMPORTED_MODULE_0__);
/* harmony import */ var https__WEBPACK_IMPORTED_MODULE_1__ = __webpack_require__(2);
/* harmony import */ var https__WEBPACK_IMPORTED_MODULE_1___default = /*#__PURE__*/__webpack_require__.n(https__WEBPACK_IMPORTED_MODULE_1__);
/* harmony import */ var url__WEBPACK_IMPORTED_MODULE_2__ = __webpack_require__(3);
/* harmony import */ var url__WEBPACK_IMPORTED_MODULE_2___default = /*#__PURE__*/__webpack_require__.n(url__WEBPACK_IMPORTED_MODULE_2__);
void function () {
  isSupportedRange('http://baidu.com').then(function (bool) {
    // ...
  });
}();

// Removed

function isSupportedRange(url) {
    // No problem!
}

tsc:

"use strict";
exports.__esModule = true;
void function () {
    isSupportedRange('http://baidu.com').then(function (bool) {
        // ...
    });
}();
var http = require("http");
var https = require("https");
var url_1 = require("url");

function isSupportedRange(url) {
    // Oops! http, https, and URL is undefined!
}
