Something else to note and fix is that as it stands in the current darcs version, wikipedia and wiktionary don't work properly with any of these intelligent searches. (Probably because their urls contain the ':' character.)

I don't follow. At least with the infixr, output seems correct: .... *XMonad.Actions.Search Control.Monad Data.Char Data.List> use (wikipedia !> hoogle !> prefixAware google) "hoogle:foo" "http://www.haskell.org/hoogle/?q=foo" *XMonad.Actions.Search Control.Monad Data.Char Data.List> use multi "wiki:foo" "http://en.wikipedia.org/wiki/Special:Search?go=Go&search=foo"

Ugh, indeed. Sorry for the noise. I'm not sure what went wrong earlier. I've too many ghci's open, and just recently cleaned out my ~/.cabal from old versions of xmonad and rebuilt clean with the infixr. So must have had wrong versions of something loaded. On the bright side, the counterexamples I needlessly dragged out of you clearly demonstrate how much cleaner is the properly defined !> in comparison with leaving it as is. thanks, Gwern. -- wmw
