I think many solutions have been given to this as well.  Here are some
for those that don't like pointers (again):

  void f( dumb_ref< T const > in_ );
  void f( dumb_ref< T > inOut_ );
  dumb_ref< T > f(); // out

Don't these address the problem of tracking down what functions change
variables that aren't copyable?
