We have some RFC for parser rewrite using lemon : https://wiki.php.net/rfc/lemon

And AFAIR, adoy has a full working rewrite just as-is, the main topic
with lemon was to make the parser thread safe, not to generate an AST.

Writing a parser / compiler for using an AST is a very huge task, so
that might be done.
