X Just asking, as my engine knowledge is a bit limited, Wouldn't it be possible that when OPcache would optimize away the unused variable assigned to a function, it could detect that that function have the NoDiscard attribute and also remove the attribute effect (warning triggering). Or identify that the function has the NoDiscard attribute and based on that do not optimize away the variable? -- Alex
