### Description
The following code:
```php
<?php
interface I {
public string $prop {
set(int|string $value);
}
}
class C implements I {
public string $prop;
}
```
Currently does not produce an error, but should, because the implementing class does not satisfy the
set(int|string) constraint.
Alternatively, explicitly specifying the set parameter in an abstract hook could be forbidden.
