I haven't tested it thoroughly (I actually have a big script set for
this purpose), but so far it seems to be doing pretty well.

.u'u sai

I'm so sorry; I phrased that poorly and I've been rude to you.

Yes, this solution is *substantially* better than the extant trick
that the official parser uses.  I'm particularily curious to see what
code can be removed with this version (i.e. the error handling
code).  For the record, looking at the changelog seems to indicate
that %prec may not actually have existed when the official parser
was made.

I'm just disappointed that this doesn't seem to put us any closer to
an actual CFG for Lojban (not that I've analyzed it properly; been
busy).  I was way too excited when I saw your first post.  Sorry if
I was an ass.
