And because they use a different underlying parser algorithm, even if
they described exactly the same grammar, they'd want different BNFs.

I think that merging the two will require some way to give
a higher-level description of the grammar which gives enough hints about
what goes to SMIE and what goes to Semantic (and what is shared).
