Passing a closure from front end to back end (just a dream)

gistfile1.aw

A Closure object doesn't have a way to return its code as a string (i.e., like JavaScript has), so, it won't work.

@ front end (PHP >= 5.3):

    $calls = new ClosureCall(
        function ($a, $b) { return $a + $b; },
        array(1, 2),
        "var_dump"
    );

    // Note: no back end specified!
    $ipc = new GhettoIPC(new FileDriver, null, $calls);

Implications:

How to execute the back end without a file in back end?
GhettoIPC would detect the existence of ClosureCalls in the queue and add a piece of code instantiating GhettoIPC and invoking its execute() method? (ugly: using '-r')
What if there are any Call/StaticCall/ObjectCall objects in the queue?
Variables in 'use'...
(...)
