Yeah, the problem is that Tom had that project about half done :-( ...
I think that the bison grammar has the support but then nothing gets done
with it in parse analysis. Probably by the time you'd worked out where
to throw the error, you'd know enough to fix it to work properly.
We could instead rip out the grammar support, which wouldn't take any
complicated analysis, but that seems like going backwards ...
