The note_stores interface doesn't really provide a way to handle PRE_DEC or other such expressions. We could change that by redefining the interface, but we would need to audit all the calls to note_stores. That would be a good idea in any case since it is certainly possible, even likely, that some of them should be handle autoincrement expressions but aren't. Ian
