static functions and array_map - why not allowed?

["Marc Weber" <marco-oweber@xxxxxx>]

Why can't I use static functions in array_map?

Example:

<?php
class Dummy
{
  static public function T($a)
  {
    echo "T called with $a\n";
    return $a+2;
  }
}

function t($a)
{
  echo "t called with $a\n";
  return $a*2;
}

echo 'invoking Dummy::T works fine : ', Dummy::T(3),"\n";
var_dump(array_map('t',array(1,2)));
var_dump(array_map('Dummy::T',array(1,2)));
?>
