I just released `@coderspirit/lambda-ioc` v0.5.0:

This new version improves its support for asynchronous resolution, in a completely type-safe way.

I would say that at this point, although it's a quite experimental library, it's starting to be production-ready (and I'm gonna be using it for real use cases).

Comment for TypeScript dark wizards:
It has been really challenging to keep the type safety for this new feature.

In order to make it possible, I had to renounce between the clean split between "containers" and "combinators", so I could leverage the type information that is available inside the container scope.
