It's not and we should probably mention it. I was mulling this over last night. My initial thought was that it shouldn't matter as long as the algorithmic complexity of the functions is maintained. But it is important in that a lookup following an insert might do all the work of the insert, which is somewhat surprising (and inefficient). > An important property, although may be non-trivial to formulate while > keeping the implementation abstract. Perhaps we could talk about the presence or absence of thunks of a Map that's in WHNF? -- Johan _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
