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?
