sorry, that this is repeat.
It is as #18274, #8702 bags and we wont solution this problem.
We wont use this construction becouse this have common sense.
We wont use result as argument if it possible.

I create same object and use in metod this code, but it create error.

class MyClass {
    function Some_One_Function() {
        if (!empty($this->MyFunction())) echo 'Some one';
               //this error?
    }
    function MyFunction() { return true;}
}

But in all changes I very like PHP. Thank you for all.

Reproduce code:
---------------
class MyClass {
    function Some_One_Function() {
        if (!empty($this->MyFunction())) echo 'Some one';
               //this error?
    }
    function MyFunction() { return true;}
}


Expected result:
----------------


Parse error: parse error, unexpected '(', expecting ')' in ...
And I now use:

class MyClass {
    function Some_One_Function() {
        $em=empty($this->MyFunction();
        if (!$em)) echo 'Some one';
    }
    function MyFunction() { return true;}
}

But it isn't logic!

Actual result:
--------------
I think, that if it worked, it would be very convenient.
