You can express a lot of concepts just through types in languages with richer type systems.

  Even without a rich type system you can express a lot of things just through naming. You just can't enforce those assumptions.

    You can enforce them (statically) by other means if you’re determined enough, eg by using lint rules which enforce type-like semantics which the type system itself doesn’t express.

      This does rely on the language having a sophisticated-enough type system to be able to extract enough type information for the rules to work in the first place.
