I agree that profiling and reading code dumps can be daunting, but in
my opinion, it's better to learn these skills once and for all (and
unfortunately, these skills are still necessary given the current
level of Haskell technology) and gain insight into how to use the
compiler to get the code you want than to practice cargo-cult
programming in the form of wanton pragmas.
