Just ran into the same thing. It looks like master fixes this. To work around this using stack I:

Forked this version: https://github.com/HuwCampbell/htoml.
Made a dir in my project called "forks" Cloned my fork into it. Merged the toml4 branch into master Added 'forks/toml' to the packages list in stack.yaml

Building works. I haven't tested it throrougly enough to say if anything is broken but it seems to be handling my simple use cases.

@cies any chance of a hackage upload for 0.1.0.3?

Sorry guys for not replying earlier. I totally must have forgotten about the 0.1.0.3 release, I'll upload it to Hackage soon.

I'm also much interested in bringing the changes of @HuwCampbell back into master. @HuwCampbell, could you please elaborate on the state of your toml4 branch?

edit: Sorry did not see the PRs; looking in to that shortly.

Hackage upload is done: https://hackage.haskell.org/package/htoml

thanks @cies!
