wired

wired is an implementation of an inversion-of-control (IoC) container and may be used as the core of a dependency injection (DI) framework or simply as a way to separate config-time from runtime for services in an application. It also provides caching such that a container maintains a local copy of each service as they are instantiated.

See https://wired.readthedocs.io or docs/index.rst in this distribution for detailed documentation.
