You're comments/docs for the method can have demonstration code that is executed when you run your tests, ensuring your docs remain accurate. It's a great pattern.

I came here to say this and you beat me to it! Love this part of elixir. It's a good way to think about your functions: if you can't write a doc test, you've probably written a function with side effects.

Julia (Documenter.jl), Python (doctest) and R have (doctest) them too.
