Unnecessary dictionaries
The attached program (unzip, untar, read Main.hs) contains dictionary building and taking apart despite all types being known. To find the dictionary search for dMonad inside QS.qsort. I've tried putting INLINE on everything I can think of, but even so there is a constant dictionary being used in a pattern match. And then the method calls are slow and non-inlined, of course.
