  I figured that was the case too. But I get the feeling that's 
wrong in this case. I was hoping to have only two declared 
opAssing's, one for temporaries (without ref) and one for 
copying. Kinda like the difference between saying a=b and a[]=b[] 
for an array. Be annoying if I had to force the cast to be const 
to do what I wanted; Right?
