When using seq and _|_ in the context of categories, keep in mind that Haskell "composition" (.) is not really composition in the category-theoretic sense, because it adds extra laziness. Use this instead: (.!) f g x = f `seq` g `seq` f (g x) -Yitz _______________________________________________ Haskell-Cafe mailing list [email protected] http://www.haskell.org/mailman/listinfo/haskell-cafe
