I think I disagree with this concept. I wouldn't shed many tears if
objname and objargs got replaced with some other kind of name
representation. But I don't think that should be done incrementally,
because then we'll be in this transitional zone where it's unclear
what the right way to do things is for a long time, possibly forever.
I'd be fine with a plan to rip out objname/objargs and replace it with
something less arbitrary, but until that's done I think new code
should stick with the existing representations.
