]> I'm writing a camlp4 grammar extension for OCaml that tries to match ampersands and rewrite expressions containing them. That wouldn't be a good idea if my code contained ordinary ampersands used for conjunctions. But the code doesn't. I'm struggling how to match the ampersands in my expression rewrite rules. I've tried "&" and SYMBOL "&", which don't work -- the preprocessed file contains the original ampersands. OTOH, I've written rules which use things like "->" and work fine. Any help appreciated. -- Paul -- Paul Steckler National ICT Australia paul DOT steckler AT nicta.com.au
