The terminals are assigned a precedence, where terminals on the same
line have equal precedences, and the precedence declarations farther
down the list of precedence declarations have higher precedence.  
<tt>left, right</tt> and <tt>nonassoc</tt> specify the associativity 
of these terminals.  left
associativity corresponds to a reduce on conflict, right to a shift on
conflict, and nonassoc to an error on conflict.  Hence, ambiguous
grammars may now be used.<p>
