Yes, generator -- based on co-routines -- is more general than iterator -- which is based on functions. But the generality comes at a price.

It depends on people. From my perspective, certainly yes. But different people have different opinions. For OpenAxiom, it is certainly something I'm actively considering. | Wouldn't the | Generator thing be enough? Or is there no plan to introduce Generator to SPAD? Enough from the theoretical point of view, certainly. But that is not all to it. Personnally, I tend to consider also the effienc at which features are delivered -- but I acknowledged that is not a universal view. -- Gaby _______________________________________________ Axiom-math mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/axiom-math
