// otherwise v is ordered before s. // Specifically, values are ordered like // // store1 // NilCheck that depends on store1 // other values that depends on store1 // store2 // NilCheck that depends on store2 // other values that depends on store2 // ... // // The order of non-store and non-NilCheck values are undefined // (not necessarily dependency order). This should be cheaper
