Ahh, I've happily found out that this is also possible in C# :-)  Something 
like:

class QString
{
        public String __value__;
        public static implicit operator QString(String s)
        {
                QString retval=new QString();
                retval.__value__=s;
                return retval;
        }
}
class Foo
{
        QString x="x";
}

Now, add the translation stuff in there and we might have something that'll 
work :-)  This wasn't your original meaning, but somehow a great idea came 
out in the wash! Thanks Ashley :-)
