Description:
------------
For the unknowing, pickle is the python derived term for object serialization. Currenlty, session management has such functionality, but this functionality is not exposed to the programmer to be done outside of using a session. I propose there be a pickle/unpickle function that uses the same serialization method that the session managment uses.

Reproduce code:
---------------
$foo = array(1, 2, 3)
$string = pickle($foo);

echo $string;

$bar = unpickle($foo);

echo $bar;
print_r($bar);

Expected result:
----------------
a:3:{i:0;i:1;i:1;i:2;i:2;i:3;}

Array
Array ( [0] => 1 [1] => 2 [2] => 3 )
