Description:
------------
From PHP 7.2 dropping the return type for methods in child classes is meant to be allowed on method signature checks: https://wiki.php.net/rfc/parameter-no-type-variance


Test script:
---------------
class Foo{
    function method (): void  {}
}
 
// This should work in php 7.2+
class Bar extends Foo {
    function method () {} 
}



Expected result:
----------------
No error.

Actual result:
--------------
Fatal error: Declaration of Bar::method() must be compatible with Foo::method(): void in /in/3E70o on line 11
