Ok, thanks. I am not so sure how to deal with that distinction in a "categorical" manner. I suppose mutability is an imperative-style programming notion. I think the lack of mutability in functional languages like Haskell is one of the harder things to get used to but at the same time one of it's greatest strengths. In general I would like Aldor/SPAD to promote a more functional style without necessarily requiring it. > > PS: Shouldn't this discussion go to axiom-developer instead of axiom-math? > Maybe you are right but recently I have been avoiding axiom-developer since Tim made it clear that the Axiom project per se was interested primarily in documentation and the "30 year horizon". I originally included axiom-math because I thought there might still be some people subscribed there who are interested in more immediate issues in Axiom and about category theory in Axiom/Aldor. But I have to admit that the profusion of email lists about Axiom, it's forks and Aldor is confusing to me and probably to our collective disadvantage.
