cabal repl failing silently on missing exposed-modules

[Alois Cochard]

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.

Anyway, I was wondering if it would be possible to give a more helpful
error message in such case.

Cheers
