]This sort of thing has been tried before.  One problem is that the displayed
]sentence is *not* meaningless in any normal sense of this term.  We
]know perfectly well what it means -- and that's the problem.

The term "meaningless" is ambiguous here.  There are many examples of
problematic meanings in language.  For example, what does the word
"unicorn" denote?  What does "nothing" denote?  Clearly, both words
have a meaning in some sense, but neither has a "normal" denotation.
If you take the view that sentences denote their truth values, then
the liar's paradox can be taken as another example of the same thing.
