Description:
------------
<?

//#1

function test1(){
	return __FUNCTION__;
}

echo test1()();

//#2

function test2($var){
	return array($var=>$var);
}
echo test2('test')['test'];


?>

Why these things are not implemented in PHP5? And when are they going to be?


Reproduce code:
---------------
<?

//#1

function test1(){
	return __FUNCTION__;
}

echo test1()();

//#2

function test2($var){
	return array($var=>$var);
}
echo test2('test')['test'];


?>

Why these things are not implemented in PHP5? And when are they going to be?


Expected result:
----------------
<?

//#1

function test1(){
	return __FUNCTION__;
}

echo test1()();

//#2

function test2($var){
	return array($var=>$var);
}
echo test2('test')['test'];


?>

We don't have $var=>$var, use $var->var.

Besides that noone reading your code will know what you want. For example what is 'test1()();' supposed to do in your oppinion?

Ok, i thought it's rather easy to understand.

#1:

$test=test1(); //$test="test1";
echo $test();  // echo "test1";

So why there is no way just to write test()(), which means run variable function that is returned by another function?

#2:

array($var=>$var) construction means i'm creating an array with 1 element which has key $var and value $var.

$test=test2('test'); $test=array('test'=>'test');
echo $test['test']; echo 'test';

So why there is no way just to write echo test2('test')['test'], which means to get an element of array that is returned by a function?

Thanks.
