Ha. ha-ha. No.

I don't really care. What I really want is to be able to say:

CONTEXTUAL-TRAVERSAL-SPEC:
  TRAVERSAL CODE

I don't really care how it gets spelled. In the current system, I
_have_ to break the context spec up on multiple lines, _despite_ the
fact that we have list comprehension semantics. I'd like to see a
solution. This one seems much simpler than the list comprehension
semantic loops I proposed earlier, so I thought it would recieve some
sympathy. Aparently it doesn't, which kinda bums me.
