I would say this: * non-strict semantics require that no argument is evaluated unless needed. * lazy evaluation is an implementation of non-strict semantics in which no argument is evaluated more than once. As an example of something other than lazy, normal order reduction is non-strict, but arguments may be evaluated multiple times. -- Jón Fairbairn jon.fairba...@cl.cam.ac.uk _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
