Re: [PHP-DEV][RFC][VOTE] Allow abstract function override

[Wes]

Yes, yes you are :D Quick reminder:​

```php
interface iA                 { function bar(stdClass $x); }
interface iB extends iA      { function bar($x): stdClass; } // OK

class cA                     { function bar(stdClass $x) {} }
class cB extends cA          { function bar($x): stdClass {} } // OK in 7.2

abstract class cC            { abstract function bar(stdClass $x); }
abstract class cD extends cC { abstract function bar($x): stdClass; } //
Fatal error: why?
         class cE extends cD {          function bar($x): stdClass{} }
```
