FYI I'm unsure how well `scope` storage class is currently 
implemented because it's in a state of flux at the moment as far 
as I know. `in ref` still helps document your intent of the 
parameter however.

It's hard to track this down exactly because scope has so many 
different meanings in D, making it difficult to search for - at 
least one of them has been deprecated.
