I can afford to correct code:
class Base
{
static function test1() {self::test2();}
static function test2() {echo 'failure';}
}
class Child extends Base
{
static function test2() {echo 'success';}
}
Child::test1();
pornel - it's ok?

How do you want to use Base, if Child class is not linked to it? :D
lol!

Ooops, code example should have "class Child extends Base" and
"Child::test1()", ofcourse.

Description:
------------
In PHP it is not possible to write base class for singleton and similar
programming patterns.
I know it is intended behavior and backwards compatibility may make
changes difficult, but there is significant number of complaints about
current implementation:

http://bugs.php.net/bug.php?id=30934
http://bugs.php.net/bug.php?id=30423

http://bugs.php.net/bug.php?id=26930
http://bugs.php.net/bug.php?id=28442
http://bugs.php.net/bug.php?id=29647
and I'd like to add another one.
I'm trying to write functionality that works similar to ActiveRow
implementation in RubyOnRails, but the way in which PHP handles static
methods and inheritance makes such implementation impossible.
I hope you could implement late binding for static calls and fields.
It could be used with this:: construct instead of self::, which may be
emulated for backwards compatiblity.
Reproduce code:
---------------
class Base
{
static function test1() {self::test2();}
static function test2() {echo 'failure';}
}
class Child
{
static function test2() {echo 'success';}
}
Child::test();
Expected result:
----------------
success
Actual result:
--------------
failure
backtrace doesn't contain reference to Child class (that would be
enough for a workaround).
