I do understand that. Making it work with the type system is another matter 
entirely - it's far more complex than just adding a qualifier. 'inout' looks 
simple but still has ongoing issues.

And the thing is, wrappers can be used instead of qualifiers, in the same places 
in the same way. It's much simpler.
