Indeed, that's the main reason I wrote my version of ppr ;) That's how I originally started my version - I was annoyed by the fact that pg's wouldn't properly print quasiquotes in my source code (and it's hard to debug macros that way) and just couldn't stop because it was so much fun.
And to be honest, I don't really know what the outstanding bugs are, or whether or not I ended up fixing them. It's been a while since I last looked at ppr.
