First, I didn't say it was a problem for languages. I was just
clarifying what Goedel actually did.
It's a problem for mathematical formalisms, and therefore potentially
for loglangs as well. For language in general, I'd say that such
metareferentiality just enhances expressiveness. I do seem to recall
that there are some theories of how human language works, mostly no
longer current and somewhat reminiscent of those mathematical
formalisms, which are invalidated by the existence of such statements.
(Proponents of those theories would simply say that no speaker would
ever "naturally emit" a sentence like "This sentence is false", so it
doesn't count.)
