Hi Taru If you haven't obviously got dispatch on type then records are certainly fine. Some obigatory examples: http://www.cas.mcmaster.ca/~kahl/Publications/TR/2000-01/Kahl-Braun-Scheffcz... (see the Editor type page 13) http://www.cas.mcmaster.ca/~kahl/Publications/Conf/Kahl-1999a.pdf http://web.cecs.pdx.edu/~sheard/papers/JfpPearl.ps Parsec's Text.ParserCombinators.Parsec.Token module is an example that has seen widespread use. http://hackage.haskell.org/packages/archive/parsec/2.1.0.1/doc/html/Text-Par...
