Hey Daniel, You were right, that is the correct way of doing it, I just found out the type I was trying to print didn't have the context at that level anymore, I had to look one position higher in the ast.

I was wondering how given a Type I can get a pretty printed type out of it.
Im currently using showSDocUnqual . pprType . snd . tidyOpenType emptyTidyEnv But this has the problem that predicates dont get printed, anyone know how GHCi does this?
