I don't agree, but for a different reason. None of the current attributes (ReturnTypeWillChange, AllowDynamicProperties, SensitiveParameter, Override, and Deprecated) change the behaviour of how a program runs. They only add warnings. with the exception of AllowDynamicProperties to be an actual 'feature' in PHP 9.0 (now it's only a deprecation warning silencer). That's the same with this suggested NoDiscard, it doesn't change how a program is run — it merely adds a warning. cheers, Derick
