Safe Numerics Library
summary
Library implements safe integer types that wrap built-ins and guarantee incorrect integer results cannot silently propagate, converting overflows and invalid conversions into throws exception on overflow or other user-selected actions. Template metaprogramming computes ranges and performs policy-driven promotion (e.g., promote operands to larger unsigned long to avoid overflow) with zero runtime cost for many promotions; source lives in Boost incubator and a C++ proposal demonstrates usage and error-policy options.
