The ambiguity in these rules lies in the shape of the parse tree as opposed
to the actual set of inputs which can be matched. I gave a more detailed
explanation and possible solutions as comments on the issue at github:

The funny thing is that Honey Badger DID support this kind of grammar (see
my earlier mail with a running example). Maybe due to a bug, but that shows
that it must be somehow possible in a top-down manner.
