Five common issues with services and dry-monads

Today I found the source code of a simple test task in GitHub. The code author used dry-monads, services, and other abstractions. I found some issues in that code and recalled that I have seen the same issues in other projects. That’s why I think that it’s a common problem and it will be a good idea to make a review and explain how we can improve our code. Also, I expect that this blog post can be useful for “junior/middle” developers and it could be boring for “senior” developers.
