 Poodinis is a dependency injection framework for the D programming language. It is inspired by the [Spring Framework] and [Hypodermic] IoC container for C++. Poodinis supports registering and resolving classes either by concrete type or interface. Automatic injection of dependencies is supported through the use of UDAs or constructors.
