21:26 CoCoALib Design #1606: Return type with const: I have changed all files which obviously need changing (after grepping for a suitable regexp).
It compiles, and all ... John Abbott

11:59 CoCoALib Bug #1605 (In Progress): binomial: domain of defn?: So the main question is: is it better to allow the fully general definition, or better to "protect the careless user"... John Abbott

10:27 CoCoALib Bug #1605 (Closed): binomial: domain of defn?: What should the domain of definition of *@binomial(n,r)@* be?
Most restrictive is *@0 <= r <= n@*.

19:31 CoCoALib Feature #1598: RingHom: implement phi(X) as apply(phi, X) also for X vector and matrix: I have a prototype for list/vector; not checked, not checked-in.
Should I check it in? Would you test it?
