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.
