I suppose I thought Lisp is useful here because Union is a low level construct
and so lisp may be needed to convert a LIST STRING object as a delisted tuple of
STRING objects to Union, just like
Union("Mass", "Length")
which works, instead of
Union(["Mass", "Length"])
which does not work as intended. I tried to do this within Axiom
interpreter/compiler and was not able to. Roughly, need a domain constructor:
Dimension(s: List String):SetCategory == Union(delisted s)
Thanks for your interest in this.
William
