Yes, you can instruct parse_string() to return multiple alternate
parse trees.

However, at this point I think it may be best to handle this problem in
LPC.  At the grammar level, it's always going to look as "give word word
word word word..." without a grammatical way to determine where OBJI
ends and where LIV starts (unless you can determine case at the token
level).  So I'd change the grammar to

    give: 'give' obji_to_liv
    obji_to_liv: words		? scan_obji_liv
    words: words word
    words:

and use scan_obji_liv() to scan for OBJI from left to right, and LIV
from right to left, and see how far you get with either.
