I would like to suggest the addition of the "self" and "static" pseudo types. Most IDEs support this through @return syntax: class Foo { /** @return static */ public function SetBar( $bar ) { // ... return $this; } } With the new syntax, the above could be transformed into this: class Foo { public function SetBar( $bar ) : static { // ... return $this; } } Lazare INEPOLOGLOU Ingénieur Logiciel
