Hi @soyuka

I forgot about it, but as promised I'll try to fix more phpstan error.
Here, I added every missing parameter type.

It's often phpdoc to unsure BC, because multiple of those method could have work with some other type (because of early return). I only added typehint is mixed or

• When the class is final
• The method couldn't have work with another type because it use another method which IS already native typed.
