I'm not sure if it's better or not but it was a surprising change between the two
versions. I'd argue that if this is the "correct" way then:
$array2 = ['foo_reference' => $foo_reference];
should also behave in a similar fashion, which it does not.

PHP 7's changes also fixed references to work more consistently.
Isn't the new behavior better? Since the variable was a reference, shouldn't the array use
a reference too?

Description:
------------
When compact() is used with references, those references are maintained in the new array in php7 and
not in 5.6
Test script:
---------------
<?php
$foo = 45;
$foo_reference =& $foo;
$array = compact('foo_reference');
print_r($array);
$foo = 50;
print_r($array);
Expected result:
----------------
PHP 5.6.17
----------
Array
(
[foo_reference] => 45
)
Array
(
[foo_reference] => 45
)
Actual result:
--------------
PHP 7.0.3
---------
Array
(
[foo_reference] => 45
)
Array
(
[foo_reference] => 50
)
