Static initializer

[thekid]

Scope of Change

Make classes have a static initializer to be able to initialize static
member variables to a class.

Rationale

Static members of a class can only be initialized to scalars in a class
definition.

Functionality

The static initializer will, if existant for a class, be called by uses().

Implementation:

<?php
  // Call static initializer
  if (is_callable(array($class, '__static'))) {
    call_user_func(array($class, '__static'));
  }
?>

Example:

<?php
  final class Console {
    public static $out, $err= NULL;

    public static function __static() {
      self::$out= new OutputStream(STDOUT);
      self::$err= new OutputStream(STDERR);
    }
  }
?>

Dependencies

PHP5
XP2
Changes to uses() functionality.

Do some benchmarking on how much this will slow down uses()
