Hi, After reading all the thread:
I'm +1 for `: static` as proposed by this RFC. I'm also +1 for `: $this`, preferably also in PHP 8.0, but that could be a separate RFC: - I like the idea to check it at compile time (like `: void`), i.e. that all the return points of the method be syntactically `return $this;` (maybe also allow `return $this->otherMethod(/*...*/);` where the forwarded method is itself declared `: $this`). - Regarding covariance, `$this` should probably be treated like a "subtype" of `static`. - I don't like the idea of making an implicit `return $this;` in addition to the check. I'm -1 for `: fluent` or `fluent function` as an alternative to `: $this`. I'm -0.5 for `: new` / `: clone`. About "what comes out is the same type as what goes in", I would wait for generics. -- Guilliam Xavier -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
