Spoken like a mathematician :) (Well, only sort of.) The way to avoid it is not to perform the work of beta conversion. Similarly, you may say that people are either dead or will eventually die, so why distinguish between a person who is dead and a mortal, live person? -- Antti-Juhani Kaijanaho, Jyväskylä, Finland http://antti-juhani.kaijanaho.fi/newblog/ http://www.flickr.com/photos/antti-juhani/ _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
