quantifiers

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.

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?)

(The book seems to think that lojban universal claims have 
existential import, ch. 16, sec. 8 [p. 399])
