I'm sorry, in the test script a $myFn() call should follow $myFn definition:
$someLongArray =array( 1, 2, 3 );
$myFn =function() use( $someLongArray as $arrCopy, &$someLongArray as $arrRef )
{
array_push( $arrCopy, 4);
array_push( $arrRef, 5);
};
$myFn();
print_r( $someLongArray);// 1, 2, 3, 5

Description:
------------
I'd like to propose a syntax for closures that would allow to specify a name for
the imported symbol (variable). Please see test script.
Test script:
---------------
$someLongArray =array( 1, 2, 3 );
$myFn =function() use( $someLongArray as $arrCopy, &$someLongArray as $arrRef ) {
array_push( $arrCopy, 4);
array_push( $arrRef, 5);
};
print_r( $someLongArray);// 1, 2, 3, 5
Expected result:
----------------
Expecting such syntax to be supported in the future.
Actual result:
--------------
Syntax error.
