I went ahead and implemented something along these lines.  The code is a
bit hairy still:

  http://svn.badgers-in-foil.co.uk/metaas/trunk/src/java/uk/co/badgersinfoil/metaas/impl/antlr/

These class allow me to parse a document in my chosen language, insert
new nodes into the AST, and then simply seralize the updated list of
tokens back to a stream (given huge efforts by the application to insert
all the extra non-AST tokens, of course).

I hope that's of use to someone else one day :)


ta,
dave
