Hi all,

I’ve spent the last few days working on Exercise 12, at the end of Chapter 5 of Ralf Hinze’s paper, “Fun with Phantom Types”.
(Thanks, Conal, for all the help!)
I thought I’d share my code, in case anyone else happens to be in the same Haskell space-time as me, right now. :)


I hope everyone is enjoying their weekend.
