We could check for mutability and accordingly raise exceptions in !  
methods. Every string created by Ruby would be mutable anyway, we are  
only talking about non-mutable NSStrings received from ObjC, which I  
don't think are a big deal. But if we want to be truly compatible on  
the other side too... we will have to find a solution.
