Hence, I abandoned camlp4 except for its ocpp incarnation with its quotation expansion support. I have written a short patch to parsing/parser.mly to support my syntax, but I am unable to get anything sensible out of it. I'll look more into this problem and post the patch if I manage to figure things out.
