That's part of the basis for Hinze's paper on memoization: http://www.informatik.uni-bonn.de/~ralf/publications/WGP00b.ps.gz > It's always nice to see that I havn't learned the elementary power > calculation rules for nothing :-) More generally, all of Tarski's "high school algebra" axioms carry over to types. You can see the axioms here: http://math.bu.edu/people/kayeats/papers/saga_paper4.ps That proves type theory is child's play :-) -- Dan _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
