Thanks for noticing that, @cartazio. The Hackage version of hermit hasn't been updated since GHC 7.10.1, and GHC 7.10.2 made some pretty important changes involving TcLclEnv (to allow threading of CallStack information, IIRC).

@xich, do you think the current state of hermit is ready for another Hackage release? I'd do so myself, but I'm not in the maintainer group at the moment.

@RyanGlScott Yes, we should do a release (1.1.0.0) for 7.10.3.

There are still some outstanding issues to solve for GHC 8, so if you do a release (I added you to the maintainer group, but don't feel obligated), please constrain the version of the 'ghc' package to '== 7.10.3'. (7.10.1 and 7.10.2 were broken anyway.)

If you don't release it, I can probably find some time later tonight.

@cartazio Thanks for pointing it out!

[cartazio]

sweet! I've never used hermit, but since some of the changes in 7.10.3 were aimed at making sure fusion (and hermit) worked, I figured I should try it out!

(also figured i should learn this whole rewrite based vocab engineering thingy)

[RyanGlScott]

Uploaded hermit-1.0.1 to Hackage. Please reopen if there are any other installation issues.

seems to build! I still need to try things out and stuff, but it installed!
