I would like to know if there is any diference between declaring
NOT token as %left or %right in the next grammar and why if i
declare as %token exists 2 shift/reduce conflicts.
| expr AND expr
| expr OR expr
| NOT expr
[Without the precedence, expressions are ambiguous:
NOT A AND B is it (NOT A) AND B or NOT (A AND B) ?
