No special reason. The Maybe struct is usually pretty small so using ref 
didn't occur to me, but if it's good practice I should do so. I suppose 
ref would be necessary because T could be a struct. I hadn't thought 
about const at all yet.

BTW show is just a test function, I recently made it private.
