Description:
------------
Using argument swapping with *printf you get a parse error thats the same as if you included a variable in the string. 

Reproduce code:
---------------
class Slaughter
{
  const pig = "%1/$s is dead!";
  
  public function __construct(){
    printf(self::pig,'Oinker ');
  }
}
new Slaughter;

Expected result:
----------------
Oinker is dead!

Actual result:
--------------
Parse error: parse error, unexpected '"' in <> on line <>
