When you say "replace with ref", does that mean 'ref' won't 
appear in the common case?

ref T fc(scope int a) {}

The problem would be that 'scope' would behave differently, 
implying 'ref' with a value type, from with a reference type, in 
which it shouldn't imply 'ref'. I don't know if it makes sense to 
automatically promote the meaning of 'scope' to include 'ref' for 
value types while leaving it alone for reference types. This was 
objected to by others, but if it were provably harmless to allow, 
it would be an appearance improvement.
