In very rare occassions I don't need to keep the object and I am fine
with garbage collection.
From garbage collection in PHP I know less, but isnt it so that:

function blub() {
 $foo =3D new O();
// do long other stuff
}

gc's $foo only after the method is finished?

function blub() {
new O()->doSomething();
}

would enable to collect this object before method ends. I am not sure
if that works with php, but it might.

That is exactly what I would love to see in PHP. Notation is also very
similar to java notation.
