Component Injection should not create global variables

Currently, component injection on the implementation side introduces static global variables - which are not a good idea in my opinion to introduce.

My suggestion would be, that we refactor component injection on the global level, and rather make it a feature of specific objects themselves. All classes that are created as return or out value of a method of an object would automatically "inherit" the injected component.

This would make a pattern very straight-forward, where people create a global context (like an "App" object) - and then use this as starting point for all further operations.

首先跟踪实现侧的组件注入，以及方法返回值和 out 值的对象创建路径。定义注入组件应如何从上下文对象继承，然后验证重构移除了静态全局变量，同时保留对返回对象的注入。
