Here is the simplest possible way to print core in the Main.hs, by the way:

That's taking GHC 8.0's Main.hs and patching it.

Hi Bill,
I use a different approach, using docker, and that's to use a patched `Main.hs` (https://github.com/chrisdone/prana/commits/master/ghc-8.0/Main.hs) and compile GHC with that patched file. It's a little unorthodox but has so far been highly effective.
Here is a repo of a core interpreter I've been dabbling with: https://github.com/chrisdone/prana
Here I have a Dockerfile that copies my edited version of `Main.hs` and builds base, ghc-prim and integer-gmp together into an isolated package database: https://github.com/chrisdone/prana/blob/master/Dockerfile.ghc-8.0#L56-L114
My Main.hs writes a .prana file for every module. At the end of the Dockerfile, I export that to a .tar.gz archive: https://github.com/chrisdone/prana/blob/master/Dockerfile.ghc-8.0#L113
Then I have a set of scripts https://github.com/chrisdone/prana/tree/master/scripts To build the image, and one to copy the libraries to the current directory under `libraries/`.
Hope that's of some help!
