Hi,
I'm not sure if that relate to this problem so please ignore me if not.
I had to spend quite a lot of time understanding what the issue had, when as you I had forget to add an entry for `exposed-modules` and trying to build...
Basically I had an error saying that a symbol was missing or something like that (can remember the exact message), but every time I have that issue it take me a while to realise I have forget the entry...
I think it's not a type error, it's kind of a linking error maybe that's why the repl fail silently.
