I’m sure it’s not right (as was pointed out a while ago). I was in too much of a hurry to get to the next bit, namely giving a description of the difference between non-strict and lazy. Perhaps what I should have said to be almost as succinct but this time accurate is “non-strict semantics requires that the evaluation strategy terminate if there is any evaluation strategy that terminates”? -- Jón Fairbairn jon.fairba...@cl.cam.ac.uk _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
