Or, in a true grammar of Lojban, tu'a would belong to a different
wordclass.

The second x is unbound.

In which case, we are also disagreeing about the meaning of Fx,
since F is not being treated as a function.

When you have true functions, treating them as predicates
involves redundant quantification (or some other redundant sort
of gadri use). Transparent LAhE avoid this redundancy.
It is unfortunate that there is no counterpart of {fi'o} that
turns a selbri into a LAhE, so that {xi'o mamta ko'a} would
mean "ko'a's mother". I can't just propose it as an experimental
cmavo, though, because it would involve a grammar change.
