However, one of the Haskell projects I work on is Ben Lippmeier's DDC compiler. Thats about 50000 lines of Haskell code and finding performance issues there is really difficult.
Right. It can still be tricky. I think we can get rid of a large number of strictness issues by using strict data structures more often, this should help beginners in particular. For the rest better tooling would help. For example, a lint tool that marked up code with the strictness information inferred by the compiler would be useful. I had time to write one I would make the output look like HPC html reports, with one color for strict function arguments and one color for lazy function arguments. Johan
