As seen on #haskell, from an idea by Malcolm,
14:42 ?let top'n'tail = ("<pre>"++) . (++"</pre>")
14:42 lambdabot> Defined.
14:43 dons> > L.top'n'tail "foo me now"
14:43 lambdabot> "<pre>foo me now</pre>"
14:43 mauke> that reminds me, haskell needs don't
14:43 dons> yes!
14:44 pkhuong-> mm. the opposite of do, eh? do for comonads? :)
So now a prize to the person who comes up with the best use for the
don't :: ?
