 Both docs and specs are attached as metadata of module once it's compiled and saved as `.beam`. In reference to the example of `App.Account` context, it's possible that `App.Account.Users` will not be saved in `.beam` file before the `delegate_all` macro is executed. Therefore, first, all of the modules have to be compiled, and saved to `.beam` and only then we can create `@doc` and `@spec` of each delegated function.
