Extremely understandable - to be blunt, I don't really feel that Haskell is ready as a general-purpose production environment unless users are willing to invest considerably more than usual. Not only is it not as "batteries included" as one might like, sometimes it's necessary to build your own batteries!
Ironically, the simple task of reading a file is more work than I expect precisely because I don't want to bother to handle exceptions. I mean, in some applications it's perfectly OK to let an exception go to the top. But in Haskell, you cannot read a file line by line without writing an exception handler, because end of file is an exception! as if a file does not normally have an end where the authors of these library functions came from? For the author of the original post ... can't make out what you actually found and tried, so you should know about "catch" in the Prelude, the basic exception handler. Donn Cave, donn@avvanta.com
