Main decisions

1. Dependency resolving is async by default:
2. framework was developed mostly for usage with async python applications;
3. sync resolving is also possible, but it will fail in runtime in case of unresolved async dependencies;
4. Container is global:
5. it's needed for injections without wiring to work;
6. this way most of the logic stays in providers;
7. Focus on maximum compatibility with mypy:
8. no need for # type: ignore
9. no need for typing.cast
