Description

The following code:

<?php

function foo(int $param_optional = null, int $param_required) {}

Resulted in this output:

(no deprecation warning triggered)

But I expected this output instead:

Deprecated: Optional parameter $param_optional declared before required parameter $param_required is implicitly treated as a required parameter in […]```

It seems having a nullable parameter will prevent the deprecation from being triggered. See https://3v4l.org/biVG1#v8.1.2 for a comparison.
