Exactly that has bothered me for long.
If I want to make a proper cabal package with tests for internal API, I
have to expose the internal API (otherwise we get double building).
In general, I always recommend exposing all the code in .Internal
modules - I often run into problems with packages that don't do this.
Yet, the whole re-exporting overhead introduced by this is cumbersome,
and it doesn't make haddocks nicer either (e.g. when you come to a page
that is full of re-exports). I hope haddock will find a way to make this
