It looks like your library is going to duplicate much of the functionality of
the library I'm going to submit for a formal review in a short time: Boost
Constrained Value library (see docs here: http://rk.go.pl/r/constrained_value).
In brief, the library is about creating wrappers for objects that allow only to
assign values valid according to a predicate. The library doesn't contain
SafeInt functionality, however, because I feel that the issues of constraining
the set of possible values and avoiding arithmetic oferflows are separate and
should be addressed by distinct libraries.

I think you may find some other useful information searching this group's
archives, there were several discussions on similar topics in the past.

Best regards,
Robert
