[Jens Gutzeit <lojban@65536.org>]

While reading "Lojban for Beginners" I found several possibilities
to refer back to sumti already mentioned. Are there any
restrictions in their usage? I know, that {ri} cannot refer to
{ko'a}, but {vo'a} can, ... But is {la .iens. djuno fi vo'a fe le
du'u la .anias. nelci la .iens.} the same as {la .iens. djuno
fi ri fe le du'u la .anias. nelci. la .iens.} or {la .iens. djuno
fi vo'a fe le du'u la .anias. nelci ra}?

mu'o mi'e .iens.
