I would rather simply add "jo'au zantufa xi pire",
because this parser supports left-association of BO (though {ku} or
{cu} become necessary after {la CMEVLA} because it supports also
cmevla as tanru unit):
([CU {broda VAU}] [i ca bo {CU <brode VAU>}] [i
{te zu'e} bo {CU <brodo VAU>}])

Any reason you think it should change from right- to
left-grouping? I mean, we just have to pick one and stick with it.
Also, in your parse it looks like there's no grouping at all...

First, left-grouping is the same as most of other grouping
rules of Lojban.
For example, a string of tanru units is read as
left-grouping:
((broda brode) brodi)
((broda ja brode) ja brodi)
I rather don't understand why only BO and CO should support
right-grouping among many other connectives.
Secondly, just the same problem as la piier raised. When I
first wrote a logical proof on "individuals" in Lojban, I should
first mention "these BO-s are regarded as left-grouping":
broda
iseni'ibo
brode
iseni'ibo
brodi
....
Right grouping of BO is very annoying for me.
We see no grouping at all on the parsing tree. It's the same
thing for JA-connection or simple string of tanru units:
http://mw.lojban.org/extensions/ilmentufa/camxes.html
([broda {ja brode} {ja brodi}] VAU)
I guess it is because of PEG's characteristic (na'e birti). I
heard about left-recursion problem of PEG. PEG first parses a
string like
broda brode brodi brodo
as
(broda (brode (brodi brodo))).
We should therefore modify the grouping after parsing.
