戻りtrue呼ばれるタイプは、実装の照合順序でrhsによって参照型を、先行する場合。何の保証は、特に指定されていない、照合順序は、同じプログラムの呼び出しの間で変更することができます.
Original:
Returns true if the referred type precedes type, referred to by rhs in the implementation's collation order. No guarantees are given, in particular, the collation order can change between the invocations of the same program.
