      What is the best way to test "compiler-heavy" code in @rustlang? Making sure that certain constructs (e.g. procedural macro applied to a struct) compile or that certain combinations DO NOT compile. The only thing I have found so far is compiletest_rs, should I start from there?

      That's what I use, too.

      Very speculative, but worth a shot: is there any way to "intervene" on compiler errors to return something more relevant to the user? Seeing the current state of typenum I imagine that the answer is no unfortunately :/

          I opened a thread in the internals forum, let's see if there is any opening.

          Typenum will hopefully soon be obsoleted by const generics, which should allow far better error messages. There are a few ways one can customize error messages, via special macros or annotations (e.g. `#[must_use(..)]`), but they cannot easily be applied to things like typenum.

          Yes, Typenum should be superseded, quite exciting! But for projects like Frunk I don't see any major improvement on the horizon.
