struct RCThing
{
  RefType *instance;

  this(this) { IncRef(instance); }
  ~this() { DecRef(instance); }

  this(this) scope {} // <- scope instances don't need ref fiddling
  ~this() scope {}
}

Or various permutations along those lines.
Ie, library types may eliminate their ref fiddling when they are scope.
