This is a nice and well thought proposal.

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;
  }
}
