The precedence shift/reduce resolving system works so that it looks 
at the token immediately before the "." in the reduce rule, and the 
token immediately after the "." in the shift rule, and use the 
defined token precedences (%left, etc.) to make a choice. If your 
rules are not on this simple form, it will not work. So then you may 
decide to rewrite your grammar.
