Thanks, this is news to me! I never noticed that ref was actually 
a function attribute.

The following are legal declaration statements:

     extern(C) void function() foo;
     pure void function() bar; // not just linkage attributes

So I think it's a plain bug that this isn't:

     ref void function() foo;
