Of course.  Again, though, I'm not aiming for bug-for-bug compatibility
with the current grammar.

In the YACC grammar, yes, but that's not the word's definition:

 zei       ZEI      lujvo glue
                    joins preceding and following words into a lujvo

OK, so what would you say that "zo broda zei broda" is, then?  I
certainly don't know.  If I had to pick one, I would say that it's
"(zo broda) zei broda"; i.e. "'broda' type of broda".

Good point, but not terribly helpful for the ZO + ZEI case that I can
see.

If one is using the concept of tokens, I suppose it does, yes.
