One of the issues I have with many of the various alternatives is that they make definition of new functions operating on Expr also impossible (by a third person) without intimate knowledge of the representation of Expr, or modifying the Expr domain. In contrast, in Haskell or Boot codes, once I give that data type definition, people are free to add more operations without knowing more of the internal representations. That is not quibbling. -- Gaby _______________________________________________ Axiom-mail mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/axiom-mail
