Roger,

Thanks for the advice. I actually figured this out after I sent my request.
I suppose my concerns come from a stronger type-checking tradition to keep
control over the types of objects being declared and passed around. However,
I can live with the softer Objective-C/Swarm approach.

Thanks for the help, Bohdan


PS: An observation: after creating aSet, we get that

        [[aSet class] name] is Set_c
