PHP 5.3 lets you do that 
I tend to find that those that use eval don't know the language well enough to do it any other way. There are very few cases to use eval. Your example can be done with the following code:
PHP Code:
<?php
class Foo {
public static function bar() {
return 'bar';
}
}
$foo = 'Foo';
$result1 = call_user_func_array($foo . '::bar', array());
echo $result1;
$result2 = call_user_func_array(array($foo, 'bar'), array());
echo $result2;
// $result3 = $foo::bar(); works in PHP 5.3
// echo $result3;
