The rules are still useful for sumti tcita and in theory all tense
constructs should be semantically equivalent to some sumti tcita construct.

puze'a means "pu da ku ze'a de ku" appropriately places in the sentence
for some values of da and de. I thought you had explicitly defined things

That's the game we played with PA, as I understand it, and now we have
debates over the meaning of some of those undefined strings.
