Javascript TypeScript Mixins 和构造函数名称

我有这个代码样本，用来测试TypeScrip中的Mixin.然而，它没有返回我预期的结果.

它应该给我User ({"id":3,"name":"Lorenzo Delaurentis"})分.

相反，我得到的是:Function ({"id":3,"name":"Lorenzo Delaurentis"}).

let Name = Class.constructor.name线应该给我打User分，但事实并非如此.我是不是漏掉了什么明显的东西？

type ClassConstructor<T> = new(...args: any[]) => T

function withDebug<C extends ClassConstructor<{
    getDebugValue(): object
}>>(Class: C) {
    return class extends Class {
        constructor(...args: any[]) {
            super(...args)
        }

        debug() {
            let Name = Class.constructor.name
            let value = this.getDebugValue()
            return `${Name} (${JSON.stringify(value)})`
        }
    }
}

class DebugUser {
    constructor(
        private id: number,
        private firstName: string,
        private lastName: string
    ) {}

    getDebugValue() {
        return {
            id: this.id,
            name: `${this.firstName} ${this.lastName}`
        }
    }
}

let User = withDebug(DebugUser)
let user = new User(3, 'Lorenzo', "Delaurentis")
console.log(user.debug())

另外，我的数据是tsc mixins --target ES6分.否则，我会得到一个错误:error TS2339: Property 'name' does not exist on type 'Function'.
