Another potential benefit - runtime metaprogramming. All types are erased when converted to JS, but I can imagine a lot of utility for runtime types in Typescr

  Obligated mention of runtypes (https://github.com/pelotom/runtypes https://github.com/pelotom/runtypes) that bridges the gap between type-land and runtime-land. It's not seamless at all but if you have a serious need for this sort of thing, it's great

    I think there is some experimental decorator syntax which will allow for extracting type info. Does runtypes interop with that? Or is planning to?

      there's the reflect-metadata package but the type information it exposes is very limited, "object" instead of {a: "foo"} and so on.

    Not quite the same, but reminds me a bit of yup (https://github.com/jquense/yup https://github.com/jquense/yup)!
