I understand why it's good, and I agree. The harder question is whether

But we're not targeting PHP for in-kernel packet filtering. And we
should not sacrifice language semantics for minuscule gains in
performance.

right.
I don't see any reasons for types, if they are not guaranteed anyway.
Well, we already have parameter types, and they are not guaranteed
either - you can reassign variables.
They guarantee the type of argument on function entry.

What I'm saying is maybe it's fine.

Because if you unset() a property it's type is not guaranteed anymore.
Can't we fix it? I mean, when we unset property on an object, we're
still keeping the definition in the class, right? Can't we use it?
I didn't understand.

Hi,
Unsetting properties is used by a range of libraries I am aware of, including
Doctrine (actually any project that relies on proxy generation).
Breaking this "feature" would be a catastrophe to a lot of projects.
There is an alternative tho

I agree that we need a way to that, but I would rather see it
