Hi, Two comments about the docs for Data.Maybe on www.haskell.org/: 1) The documentation for the "maybe" function ends with: "Otherwise, it applies the function to the value inside the Just and returns that." Returns which? I think this should read: "Otherwise, it applies the function to the value inside the Just and returns the result." 2) The documentation for mapMaybe ends with: "If it just Just a, then a is added on to the result list." First, I think "Just a" and "a" should be "Just b" and "b", or "Just v" and "v", etc. The reader may think these a's are the same a's in the type, which is not the case. Also, the phrase "added on to the result list" is misleading, I think. So my suggested alternative is: "If it just Just b, then b is included in the result list." Hope this helps. -- Paul
