I think that right solution would involve list of non-type template
parameters, which would allow static control of ranges at type level.
There is place for runtime range control, though:
* as a tool which can be used in implementation of user defined
operators (especially - + *) and conversions
* as a specific implementation of getter/setter interface

I also think that more general getter/setter (possibly allowing
callbacks to "target" class) would fit in this picture.
