Were you thinking of something like "[n] Things a Java Programmer Should Know About Ruby" ? http://jimweirich.tadalist.com/lists/public/14055 Perhaps you'd like to start a page on the wiki. A link from here, maybe? http://haskell.org/hawiki/FrequentlyAskedQuestions The libraries I think I used the most when starting were: Data.List Data.Char Data.Maybe Data.Either System.IO (reading and writing files) System.Environment (for getArgs) Data.Set Data.FiniteMap (soon to be replaced) Of course, a lot of this is already in the Prelude, so you'll be using it indirectly.

The recent post of Graham Klyne (below) reminds me that I have meant to ask: is there a ``top 20'' things a serious programmer should know when writing code in Haskell? Of course there is a lot of programming language theory that would be great to know, but I mean really down-to-earth things like the 2 items below (module Maybe, the 'maybe' function).
The Haskell libraries are quite large, and it is unrealistic to try to get familiar with all of them right away. But getting a ``small'' list would be very useful - I think of this as step 2 after one learns to get comfortable with a language. I had done this (for Maple) for training new hires at Maplesoft, and I definitely noticed that they became more idiomatic programmers faster this way.

PS: of course, this could already exist on haskell.org and/or the Wiki, but not in an 'obvious' enough place as I missed it...

You might also be interested in the library function 'maybe': http://www.haskell.org/onlinereport/standard-prelude.html#$vmaybe
or maybe (sic) Maybe.fromMaybe in: http://www.haskell.org/onlinereport/maybe.html
