Not sure, but I at least am certainly aware of possibilities that such writeups exclude. In particular, you can do (a subset of) the following in sequence: * write your own grammar in whatever bespoke language you want * compose those grammars into a single grammar * generate a Bison grammar from that grammar * run `bison --xml` instead of actually generating code * read the XML file and implement your own (trivial) runtime so you can easily handle ownership issues In particular, I am vehemently opposed to the idea of implementing parsers separately using some non-proven tool/theory, since that way leads to subtle grammar incompatibilities later.
