是否支持模块的动态加载？如何实现

// harlibrary的src/main/ets/utils/Calc.ets 
export class Calc { 
  public constructor() { 
  } 
 
  public static staticAdd(a: number, b: number): number { 
    let c = a + b; 
    console.log("DynamicImport I'm harLibrary in staticAdd, %d + %d = %d", a, b, c); 
    return c; 
  } 
 
  public instanceAdd(a: number, b: number): number { 
    let c = a + b; 
    console.log("DynamicImport I'm harLibrary in instanseAdd, %d + %d = %d", a, b, c); 
    return c; 
  } 
} 
 
export function addHarLibrary(a: number, b: number): number { 
  let c = a + b; 
  console.log("DynamicImport I'm harLibrary in addHarLibrary, %d + %d = %d", a, b, c); 
  return c; 
} 
 
// harlibrary的index.ets 
export { Calc, addHarLibrary } from './src/main/ets/utils/Calc'; 
 
// hap的index.ets 
let harLibrary = 'harlibrary'; 
import(harLibrary).then((ns: ESObject) => { // 动态import变量是新增特性，入参换成字符串'harlibrary'是现有特性。也可使用await import方式。 
  ns.Calc.staticAdd(7, 8); // 反射调用静态成员函数staticAdd() 
  let calc: ESObject = new ns.Calc(); // 实例化类Calc 
  calc.instanceAdd(8, 9); // 调用实例成员函数instanceAdd() 
  ns.addHarLibrary(6, 7); // 调用全局方法addHarLibrary() 
});
