A trouble I have in explaining things is that I use words in a technical
sense, one which is common to the literature but often completely
unknown everywhere else. :-) "Ambiguous parse" has a specialized
meaning to me and I personally would not that word here. But if you
find it helpful, that's fine.
What's going on is G1 and L0 are two different parsers, doing two
different parses, and trying to sync up. To do that, they have to agree
on the symbols they share -- the "lexemes". There are certain rules of
thumb Marpa uses, and these work a (to me) surprising amount of the
time. But I don't let Marpa carry the guessing game too far, and when
the rules of thumb don't work, Marpa throws the question back to the user.

If you use them inconsistently, it can't do this and complains. One of its

In essence this is an ambiguous or possibly even impossible parse, right?
