[Haskell-cafe] Evolving faster Haskell programs - where are the files?

I just read the enlightening article by Don Stewart[1], and wanted to test this method on one of my own programs, but it seems that there some of the attached files are missing, namely [2], [3] and [4]. Is there anybody who knows, where I can get those files? I don't really want to rewrite those file by hand.
