Since they can return a value and can be a part of an expression it is important to know their precedence. For example: ``` $state = yield from self::removeContacts($state, $command->contacts) ?? $state; ``` This code is apparently equivalent to ``` $state = yield from (self::removeContacts($state, $command->contacts) ?? $state); ``` which I would not have guessed. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=77679&edit=1
