Feature Request: Ability to specify type in decorator, to allow Class type about dynamo-types

[breath103]

Hey thanks for the suggestion

Simply told,
a) You can do the exact same thing already. if you just use interface.
b) To use the class, it requires much more work than just saying "type: Object"

1. For now, you can totally do

 @Decorator.Attribute({ name: "user" })
  user: {
    id: number;
    name: string;
    email: string;
  }

Or even

  interface User {
    id: number;
    name: string;
    email: string;
  }

 @Decorator.Attribute({ name: "user" })
  user: User;

2. "Class User" is a totally different story. "class" means "using given constructor(function)" in JS, thus

class User {
  id: number;
  name: string;
}

const a: User = {
  id: 100,
  name: "A",
}

const b: User = new User();
b.id = 100;
b.name = "A";

first one might work on compile, but it's wrong usage of class you can just check with "instanceOf"

a instanceOf A ==> false
b instanceOf A ==> true

thus, what you need to make if you really want to use "Class" is

@Decorator.Attribute({ name: "user", type: User })
user: User;

and read that type value as "Constructor" and new options.type(), and hoping it has every setter it needs.

Personally, I don't have plan to support "class" since it really breaks everything here. (There is no way we can tell the arguments definition of constructor even)
