Description:
------------
I have a class which inherits from another class. The base class has a 
private property. When I check if that property exists on the inherited 
class, it returns true.

Reproduce code:
---------------
class A {
	private $a;
}
class B extends A {
}
$a = new B;
$ref = new ReflectionClass($a);
var_dump($ref->hasProperty('a'));


Expected result:
----------------
bool(false)

Actual result:
--------------
bool(true)

From the documentation of hasMethod(), it seems that private properties also count as properties. Why do you think this is a bug? Because the property is not defined in class B but in class A?

1) Because it's a member of the base class and it's private.
2) Because the equivalent $ref->getProperty('a') throws an error, of 
unknown property

You are right. It can be expected that if hasProperty('a') returns true, getProperty('a') works. This works correctly when reflecting on A, but not when reflecting on B.

Actual:
Reflect on:  A B
hasProperty: y y
getProperty: y n

I am not sure what the expected behavior should be. I.e. whether hasProperty should return true or false on B.
