Description:
------------
Right now, any arrays that are exported via var_export use the longer array() syntax.

What would be useful here is a third optional argument to var_export:

e.g: var_export($arr, FALSE, TRUE);

Where if the third argument is set to true, the output would use the shorter, PHP 5.4 syntax.

There are already functions out there (search for var_export54) that do this sort of thing, however, it would be useful if this were in core PHP.

The third argument isn't necessary, however, I propose doing it this way to not break compatibility for existing people who are using var_export.


Test script:
---------------
$arr = [
    'key' => 'value',
    'mushroom' => [
        'badger' => 1
    ]
];

var_export($arr, FALSE, TRUE);

Expected result:
----------------
[
    'key' => 'value',
    'mushroom' => [
        'badger' => 1
    ]
]


Actual result:
--------------
array (
  'key' => 'value',
  'mushroom' => 
  array (
    'badger' => 1,
  ),
)
