I love saying this but OTP is a really roughneck standard library. They just added shit to it as they needed it without apparently putting too much consideration into the organization, naming, or conventions.

It makes it very powerful but very disorienting and experience gained with one part of it often does not really prepare you for other parts. Usually each specific tool was created by someone who used it immediately, so it's all reliable in its way. But there is a lot of redundancy and odd gaps.

Elixir's almost extreme attention to naming, organization, and consistent convention is almost as far as you can get from this approach too. It's fun to have them in the same ecosystem and see that there are actually pros and cons to each approach.
