Of course in principle both domains and categories are supposed to be treated equally as 'types' - at least in Aldor this is true. > > (6) -> x:List Integer:=[1,2,3] > > (6) [1,2,3] > --- assume that in (6), List Integer is unnamed. > Type: List Integer > ... > There is also the complication that the above is done via the interpreter. > I do not think it is possible to test this in the Axiom interpreter because it's support of types as first class values is highly deficient. But I took a try at this using Spad. See Juergen's examples here: http://wiki.axiom-developer.org/SandBoxCategories I think this demonstrate that Davenport's rules are implemented in Spad.
