Well - BigInts have become like London Buses - you wait for ages and then six of them come along ;-)
Your Xint looks interesting, Boost styled (if not Boost-style tests), and Boost licence. Docs (though not
Doxygen/Quickbook) and no examples. But these are trivial issues.
I've not been following the WG21 discussions of Bigger Integers - perhaps you can summarise their response to N1744 (was
is "we are too busy dealing with C++0X?").
PS I note it doesn't (yet) specialise std::numeric_limits?
numeric_limits is something that is very highly desirable/essential for many applications (for example the Boost.Math
package relies on this, and had to add it to be able to use the NTL package and GMP package).
NaN is essential IMO (if only to act as a 'missing value' marker (though I would favour a separate NaN for this purpose
