I think you’re conflating regular auto use with using it as a return type/argument. The latter is syntactic sugar for declaring a template. It isn’t any less “documented” than doing a template<classReturnType>....
Having the return type name is absolutely better documented. But I guess were splitting hairs because its a hard typed language and lexers can find what it is anyway.
