One of the smaller nits I noticed when looking at profiles generated by 6.8.1 (using -prof -auto-all) is that class methods show up as cost centers named something like "$f5". I can look at the call stack and figure out that $f5 is probably the call to a particular class method in a particular location, but I was wondering what it might take to make that more user-friendly (I'd want to see the class name, method name and the instance being used in some format, ideally). Is that information readily available and it is just a matter of making -auto-all smarter, or is there a reason this would be tricky? Thanks, - Ravi

You can know for sure which method in a class $f5 denotes using -ddump-simpl (and grep '$f5' on the output). Also note that this issue is currently filed as a bug. http://hackage.haskell.org/trac/ghc/ticket/1641 -- Denis
