I also think that:
$foo = (new bar())->someSetter();
is assigning the return value of the setter to $foo. I would love to
have a language feature like anonymous classes, but if $foo contains
the bar-object after this line - wow, how would I hate this. From my
understanding both examples should act differently.
Rephrased: if one would say, the constructor returns itself as a
object, you could call the someSetter() method on the returned object.
The return value of someSetter() is then assigned.
Having such a language feature could help with having that later:
$a = new AbstractClass {
public function methodToOverride() {
// overriding code
}
}
i think this already works:
$a = new MyObject();
$a->setListener( new MyListener() );
but this could then work too
$a = new MyObject();
$a->setListener( new MyFactory()->createZipCreator() );
As said, I would love such a syntax feature
cheers
