Hello,

I have quite a nested configuration file that contains a lot of lists.
I would like to inject a specific element into a provider, which would look like:

config = providers.Configuration(defaults={'index': 0, 'items': list('a', 'b', 'c')})

foo= providers.Factory(Foo, item=config.items[config.index])

However, I was prompted:

TypeError: 'dependency_injector.providers.Configuration' object is not subscriptable

Anyone has idea about this? Thank you.
