running ghci with -prof turned on makes it die immediately (with an appropriate message about this combination being illegal). however, i find that i would almost always *rather* run ghci with -prof turned on than without it. i don't particularly want to create profiles, but i'd really like stack backtraces in ghci. how much effort would be required to allow ghci to (at least) *use* profiled objects, if not build them itself? - hal -- Hal Daume III | hdaume@isi.edu "Arrest this man, he talks in maths." | www.isi.edu/~hdaume
