Thank you @germsvel for taking the time to write this proposal and summarising potential approaches. I've been using anonymous functions to date in order to address this specific issue for factories with dependency chains.

As for the proposed solutions, I think introducing a function like build_lazy would help a lot of users of this package. In particular, I think it would be valuable to new users as it draws attention to what is otherwise a usability issue which only becomes apparent through specific use cases. Building a remedy for this into the library's interface demonstrates understanding and care! I like the name of the function as well, as I think "lazy" in this context should resonate with functional programmers.

@sgerrand thanks for your response.

When you mention

I've been using anonymous functions to date in order to address this specific issue for factories with dependency chains.

Does that mean that the approach of usingbuild_lazy/2 with anonymous functions as their implementation would cause a breaking change for you? Or is that an approach that you prefer over the private data structure?

I don't really have strong opinions about either approach. I can see arguments for either direction.
