      I'm not sure I agree with this generalization. Having more first-class constructs means that—unless they're truly orthogonal—language designers and users both have to deal with the interactions between them. Implementing new constructs by composing existing ones is far superior. https://twitter.com/jdegoes/status/1091678739589545985 …

      My approach is to replace them all with modules. I think the remaining issue is purely syntactical: How to decide whether "module foo" in the first line is a "module declaration" or a module with no contents? Multiple options, including making the line mandatory, or adding {}.

      I'm not convinced that the openness of packages is as useful in Scala as in Java, except for separate compilation. Everything else we do that requires packages to be open could be done other ways. Then we could lose packages, and package objects wouldn't need to exist either

      Anyway, that's entirely speculative. I don't think they're going anywhere!
