Description:
------------
class A
{
        public function getName()
        {
                return("a");
        }
}

//Issue 1:
//This produces "syntax error, unexpected T_OBJECT_OPERATOR":
echo new A()->getName();

//This works:
$_= new A();
echo $_->getName();


//Issue 2:
//This produces "Can't use function return value in write context":
$b= " a";
var_dump(empty(trim($a)));

//This works:
$b= " a";
$_= trim($a);
var_dump(empty($_));



//In php, I must assign an expression to a variable first 
// before being able to use it at some points? Why?
