Hi. I have a labelled directed acyclic graph that I want to rewrite.
The rewrite rules are not context free but can have, potentially,
infinite lookahead. I plan to implement my parser in Prolog so the
lookahead is not an issue.

Has anyone else done this? If so, how do you specify the rewriting of
portions of the sub-graph? Particularly I am interested in specifying
these types of graph transforamtions.

Thanks for your time.
