I recently wrote a proposal:
http://www.crystalclearsoftware.com/cgi-bin/boost_wiki/wiki.pl?SecureI ntegerOperations Hi! I'm very glad someone is willing to address this problem, which seems to be neglected. ;-) You might want to take a look at SafeInt: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dncod e/html/secure01142004.asp It takes a different approach, which IMO is more convenient in most situations than the free functions, it defines a wrapper class template which controls all the arithmetic operations of the underlying type. The code is copyrighted and highly platform-dependent, but I think that if Boost is going to have any arithmetic operations checking mechanism, then it should rather look like this. Also, I think the interface containing a bunch of C-style set of functions with arguments' types pushed into the functions' names is a bit inadequate for a modern C++ library - it makes it very difficult to use your library in a generic code, and it makes it easy to perform unwanted argument conversions.
