A while ago I was investigating dependency injection frameworks for a project I'm working on in Python (part of a full-time job, moderately large and complex). I found some projects such as dependency_injector that look interesting but many of them look somewhat abandoned. The examples from those projects make dependency injection frameworks appear to use the same amount of code (or more) than simply putting a dependency between two classes/objects in the first place. I did some more reading and it looks like a similar situation has happened with DI frameworks in Ruby as well; it turned out to be easier to use dependencies directly than to code with some frameworks. Is it useful to use DI frameworks in languages that dynamically typed? I know such frameworks are often used with statically typed languages such as Java or C#. What about dynamic languages like Python or Ruby?
