Regrettably, it can't.  Whatever is done in the preparser rules (900-end) 
can't refer to things in the earlier rules, on pain of implementing the 
entire parser within the preparser.  So "NOI sentence" within a tense is 
impossible, even though it YACCs, it doesn't fit the schema of the 
parser, which is to keep the compounded forms simple.  Of these, tense 
(lexer_O) is already the worst offender, and further complications are 
truly intolerable.

I am still thinking about the other possibilities.  I weakly favor 
messing with "ve'i <sumti>", although I recognize the annoying doubled 
semantics of the i/a/u vowel plus what the sumti actually says.
