Well I mostly meant that a lot of it is like:
BAI-clause <- BAI-pre BAI-post
BAI-pre <- pre-clause BAI spaces?
BAI-post <- post-clause
${cmavo}-clause <- ${cmavo}-pre post-clause
${cmavo}-pre <- BAhE-clause? ${cmavo} spaces?
A little shorter as nobody uses ${cmavo}-post afaik.
All those can be grouped in alphabetical order one after another.
Then there are the special ones which correspond with the magic words,
all those clause ones could be grouped togheter in alphabetical(or
other) order: SI SA SU ZO ZOI LOhU LEhU ZEI BU LAhO and FAhO . I think
the Y-clause is called spaces;-) NIhO, LU, TUhE, and TO might also be
different because of how su interacts with them.
BRIVLA and CMENE might also get specialy written clause stuff.

Well I don't have any ideas on how to optimize things in that way, the
peg is fairly thinish.
I have an idea for the sa thing, but that would most likely make
things bigger not smaller.
