Hi,
About 3 weeks ago I reported this bug to Jeff Newbern. But I got no response - maybe I got filtered out as spam :) Since it was not fixed I'm trying once more here. Maybe there is somebody here who has access to the web site http://www.haskell.org/all_about_monads and cares enough to fix it.
On page
http://www.haskell.org/all_about_monads/html/writermonad.html
there is "listens" defined like this: listens f m = do (a,w) <- m; return (a,f w) ... but it should be like this: listens f m = do (a,w) <- listen m; return (a,f w) ... or maybe a less strict option (as ghc libs have it): listens f m = do ~(a,w) <- listen m; return (a,f w)
Peter.
