Description:
------------
Please add a __STATIC__ magic constant so that a static method can know the name of the class that it was called on.

In other words:
class A {
  static function bla() {
    print __STATIC__; 
  }
} 

class B extends A {}

print B::bla() . "\n"; // I want this to print "B".

http://www.php.net/manual/en/language.constants.predefined.php#84050

Test script:
---------------
// This is how it is currently done:
php -r 'class A { static function bla() { print get_called_class(); }} class B extends A {}  print B::bla() . "\n";'  
B

// This would be more consistent and convenient:
php -r 'class A { static function bla() { print __STATIC__; }} class B extends A {}  print B::bla() . "\n";'  
B

You can use the static keyword for that. See http://php.net/lsb

Sorry, misread your request.

But a constant can't be done for technical reasons. The value of the magic constant has to be known at compile time, but the lsb name is only known at run time.
