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.

Start by tracing the implementation-side component injection and the object creation paths for method return and out values. Define how injected components should be inherited from a context object, then verify that the refactor removes static global variables while preserving injection for returned objects.
