Logged In: YES user_id=31435 The grammar is correct as-is anyway, so closing this as invalid ("and" is left-associative, that's critical to correct understanding of its short-circuit semantics, and the production for and_test is left-recursive to make that clear: "a and b and c" must be parsed as "(a and b) and c", not as "a and (b and c)" as the suggested change would force).
