I found this while testing #453.

Hm interesting, I haven't had this happen to me!

Might be connected with this issue: https://github.com/kowainik/stan/issues/178 ?

I don't feel I understand the situation enough to open GHC bugs, I have to admit. What are your thoughts on this? Did you manage to fix this somehow, maybe by removing that .hie file, or running cabal clean?
