I don't even know what something like that means.

As I understand it, adding "ref" or "out" keywords adds a level of indirection 
since you're allowed to change the value of the parameter. If the parameter 
is a System.Int32, for example, the address of a System.Int32 is passed 
instead. The value is true with pointers. When you pass an IntPtr with the 
"ref" or "out" keyword, you're passing a pointer to a pointer. Unnecessary 
use of "ref" or "out" seriously complicates things.
