Right, by using ambiguous rules and manually resolving the ambiguities using
precedence directives, it should reduce the number of reductions needed. You
can also set the precedence of an operator token directly:

%left '+' '-'
%left '*' '/'

etc...

E.g. any rule with a '+' token will have the associated precedence, although
using %prec gives you direct control over which rule to apply the precedence
to.
