Implemented Dependency Injection containers in pure ✨🐍✨

I did that in C#.
Then I was asking myself wtf I‘m doing.

@Lensflare well .NET has quite a rich ecosystem around DI. The problem i had is that nothing seemed to work smoothly with FastAPIs DI system. The closest thing was dependency-injector, but the semantics behind providers and dependencies was way too confusing. And FastAPIs DI system is pretty wonky for classes, nothing felt like the beauty of how its implemented in C# or Angular.

Ah and i just dint get the design decision behind the Depends( class) in FastAPI. And especially why I can only use INSTANCES of Callable classes, which are basically stateful functions
