| specific optimisations). Of course anyone may disagree. (Btw, | documenting all the really innovative stuff in official publications will | take some time, so if you want to wait...). Robert, let me encourage you to do this writing. Debates on the Haskell libraries list have a narrow audience; a paper has a far wider audience. Furthermore, the process of writing a paper often has an incredibly beneficial effect on the ideas being described. And the paper will still be read long after the implementations it describes have turned to dust -- papers infect people's brains which is the most powerful form of software propagation of all. The Haskell workshop might be a good venue. Simon
