Bug description: $foo() syntax is too limited
Description:
------------
It's already possible to have arrays that represent callable methods
(either static or instance), and 5.3's closures offer a third type of
"callable" function.
But the $foo() syntax that facilitates calling that callable function
still requires $foo to contain a string.
Since in general one cannot know in advance just what type of callable the
value of $foo actually is, and when one does know it's often NOT a string,
it's necessary to forego the syntax and rely on call_user_func($foo).
What would be nice is if $foo() also worked in the cases where $foo was a
callable array or Closure object. call_user_func() itself would largely be
relegated to the status of "function equivalent should you need it" and
complement to call_user_func_array().
Reproduce code:
---------------
<?php
// For 5.2.x as well.
class Thing {
static function DoesStuff() {
echo 'Hello, World';
}
}
$f = array('Thing', 'DoesStuff');
$f();
?>
Expected result:
----------------
Hello, World
Actual result:
--------------
Fatal error: Function name must be a string in C:\test.php on line 11
