Research direction

Start by tracing the existing inject decorator and Injector behavior, then compare them with the container.get workaround described here. Done means the project has a decided API for selecting a specific Injector instance at decoration time and clearly defined behavior for modules with different dependency configurations.

Written by the indexing model from the issue text.

Description

This has been in my mind for some time so I decided to finally write it.

Would that be possible to specify the Injector instance that should be used to inject dependencies? I see it the following way

container = Injector([module])

...

@container.inject    # or maybe @inject(container)
def do_something(a: Dependency):
    ...

My motivation is that I have multiple python modules, each one configuring it's own dependencies so each module (in general) expects different instances of dependencies.

I know that the proposed solution requires a variable container to be defined at interpretation time but not always is that undesireable. What do you think?

My workaround currently is calling container.get but I don't really like it.

Or is there something I don't understand about how injector works and inject chooses "the most local" container?
