this code prints instance of object "b" and doesn't throw any errors or exceptions. If a::stat has modificator "static" it says "Notice: Undefined variable: this" and prints null.

Reproduce code:
class a
	public function stat()

class b
	public function test()

$b= new b();

Expected result:
throws some errors or exceptions. 

Actual result:
prints instance of object "b"

This is expected, :: calls a method of a class using th current context as call context. Hence $this in a::stat is a b object. It will issue a Strict warning.

It's kept that way in PHP5 for PHP4 backward compatibility reasons but it may be cleaned up in PHP6.
