I don't think that that will work, since "ro lo" is really equivalent
to "ro da poi ke'a" and not "ro da poi". For example, "everything I
want to eat" would have to be "ro da poi mi djica le nu citka ke'a",
and can't be converted to a "ro lo" form.

{ke'a} only turns up if needed, i.e. if the sumti to which {poi} attaches is
not in the first place, so that is not what is special here.  It may be that
it cannot be put in {lo} form, in which case, this partiuclar subject will
not use that {rolo} version.  That is, of course, one of the reasons for
having several ways of saying the same thing, but, in this case, the first
does always work (I think -- until someone fadges up a contrary case).

<For a universal quantifier with existential import, I think we can
use "rosu'o"/"su'oro", parallel to "roci", etc. for "all three". (Is
there any convention for which number goes first in these compound
quantifiers?)>

I like the idea, but I wonder if it will work.  {roci broda} comes in stages
from {ro lo ci lo broda} as far as I can remember (and this explains the
order); I think that (ro lo su'o lo broda} collapses to {lo broda}

<(The book seems to think that lojban universal claims have
existential import, ch. 16, sec. 8 [p. 399])>
Why, so it does!  I can't help feeling that this statement is contradicted
elsewhere in the relevant sense.  That is, as noted, {roda Q} always does
entail {su'o da Q}, but an unchanged Q may mean that {su'o da Q} is nothing
like "Some S is P" -- if Q is a conditional, for example, it does not
magically change to a conjunction.  If this really is uniformly covered, I
take the Emma Litella line.
