On the one hand, I agree with you - except for the part where it's a 
subtype of String, that doesn't work.  In case I haven't mentioned it 
enough times already:

On the other hand, we've all been on this merry-go-round before:

    http://www.python.org/dev/peps/pep-0355/

Note especially the rejection notice: "Subclassing from str is a 
particularly bad idea".

Again, one day I'd really like to add one of these to Python.  Now is 
not the time.
