Subject: function overriding and class inheritance
From: emil.vladev@gmail.com ("Emil Ivanov")

Hi,

I'll try get straight to the point:
class C1 {}
class C2 extends C1 {}

abstract class Work1 {
 public function f1(C1 $c);
}

class Work2 extends Work1 {
 public function f1(C2 $c);
}

Here I get an an error regarding the prototype missmatch.

Wouldn't it be nice to be able to tighted the requirement - C2 is still C1?

Regards,
Emil Ivanov
