Re: [isabelle] using Haskabelle with recent versions of GHC
Thank you for your replies. I've managed to work with Haskabelle using the
2015 version of Isabelle, and I think I'll stick with it. It works for me.
Moreover, I wrote a small script that extracts only the Haskell code from
latex+Haskell mixture. I'm not begin able to translate a few things, but
a closer look before coming back to you with further questions.
