The classic %left, %right and %nonassoc encode associativity and thus implicitly drive precedence decisions in an otherwise ambiguous grammar, which is to be frowned upon as it does hide some error types. Hence a directprecedence-only specifying instruction is called for. A bit akin to the %prec modifier.
