I checked grammar .300, and there seems to be no such distinction
between zo and zoi:

a. If the Lojban word ``zoi'' (selma'o ZOI) is identified, take the 
following Lojban word (which should be end delimited with a pause for
separation from the following non-Lojban text) as an opening delimiter. 
Treat all text following that delimiter, until that delimiter recurs 
*after a pause*, as grammatically a single token (labelled 'anything_699' 
in this grammar). There is no need for processing within this text 
except as necessary to find the closing delimiter.

b. If the Lojban word ``zo'' (selma'o ZO) is identified, treat the 
following Lojban word as a token labelled 'any_word_698', instead of 
lexing it by its normal grammatical function.

So both words turn what follows into special tokens, but remain
themselves as separate tokens.

That's not good. It causes a lot of problems. All of the
following should give error if grammar .300 is followed 
to the letter:

{zo da si de} 

si will erase the previous token, 'any_word_698', and then 
ZO followed by KOhA should give an error.

{zo da zei de}

zei will join 'any_word_698' and KOhA and turn everything 
into BRIVLA, but then ZO followed by BRIVLA should cause 
an error.  

{zo da bu}

bu will turn 'any_word_698' into BY, but then ZO followed 
by BY should cause an error.

Similar things will happen with zoi:

{zoi gy sth gy si}

will give an error because si will swallow the 'any_word_698'
token and what's left: ZOI any_word_698 anything_699 will be
followed by something else and give an error. The only way to 
recover is to add three more {si}'s to remove everything.

I think that the Right Thing is to treat {zo <word>} and
{zoi <word> <anything> <word>} as single tokens of selmaho
KOhA.

In any case, I don't see any justification for treating 
{zo} in one way and {zoi} in another.
