OK, I imagined something along these lines.

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

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.
