For what it's worth, there is an implementation in Scheme, written by Marc
Feeley. You can find it in the Scheme repository:


ftp://ftp.informatik.uni-muenchen.de:
    /pub/comp/programming/languages/scheme/scheme-repository/code/lang/earley.scm


(or any of the other mirror sites). I have no idea if it works, but it maybe
useful checking it out.
