OK, I imagined something along these lines.

Yes, I also think that this is good. Still, I really like the second name
space.

Having Aldor might help here, since then the argument to a function may be a
domain or a category or whatever. Although I must admit that I didn't check

of a domain. There is name(%)$Trace, but I cannot remember right now how
reliable that is.
