The {su'o} before the {pi} was just to explicitly make it an existential
quantifier... of course it's a horrible abuse of {pi}, which is meant to
be a decimal point, but not a new abuse.

So {su'o pi za'u ko'a}, which might or might not be the same as just {pi
za'u}, would mean "one or more subbunches of ko'a", where a subbunch of
ko'a is a sum aka plurality aka bunch (I understand these all to mean
the same things, and to agree with Chierchia's setup, at least modulo
the intensionality issues below) the atoms below which are also below
ko'a; i.e. it is any ko'e such that ko'e me ko'a, if {me} is our Among
relation.

In other words, {su'o pi za'u ko'a} would be the plural quantifier
\exists X AMONG ko'a

Naturally.

But the way I'm understanding the tense system, {lo} and {zo'e} would
only ever get evaluated *after* we've selected a world.

e.g. {mi ka'e citka lo blaci} means that in some possible world I eat
something which is glass *in that possible world*, i.e. it means
something like (ignoring all subtleties of {lo} for a moment)
\exists w. \exists b. (blaci_w(b) /\ citka_w(mi,b))

(where the first quantifier is over worlds, and the second quantifier is
over the domain, and blaci_w and citka_w are the interepretations of
blaci in the world w, being relations on the domain).

I really don't see how it could work any other way. Could you explain in
detail how you see it doing so?
