Yes. You catch an exception to keep the computation going: a := WPoint2 new x: 1; y: 0. w := WWorld2 thisWorld sprout. w eval: [a y: a y + 1]. a y: 666. [w commit] on: Error do: [:ex | ]. then you can say: b := WPoint2 new. b x: (w eval: [a x]). b y: (w eval: [a y]). to "salvage" the values of a in w into b in the top level world. There should be more first class operations allowed, and perhaps the serializability checks and commit logic should be customizable... -- Yoshiki _______________________________________________ fonc mailing list fonc@vpri.org http://vpri.org/mailman/listinfo/fonc
