Looking over Real-World haskell I see that some of these topics are discussed, which is really good. In particular, Chapter 25 would be valuable to anyone trying to find space leaks. There you discuss reduction to normal form, for example, and some strictness issues and how to control evaluation.
For some time now, I have this theory that confusion about space leaks can often be attributed to people not being informed about the evaluation model. They simply don't know what's going on; they only know that it's got something to do with these "thunks". Is that an accurate description? Regards, apfelmus -- http://apfelmus.nfshost.com
