It's much more than that! I did run and see it (proud to be the first downloader of version 0.2.1 :-)) and I'm enthusiastic. Too many times I've realized I needed something to stem the pervasive danger of Win32's all-is-a-dword typedefs and postponed the issue.
Don't get me started ;-)
This is one of those lovely pearl which combine elegance and usefulness in a way which happens to be obvious only once you have seen it. That's the Euclid algorithm of the type system! :-)
Well, it's handy, but it's only part of the story. One might argue that this utility could be combined with other 'value-type' programming tools like Boost.Enum (although I don't really care that much for some of the details of the current proposal) and constrained_value. These are small utilities that allow the quick generation of valuetypes that clarify interfaces and prevent errors.
About the name, isn't "identifier" meant as "something which gives an identity" rather than as "C++ grammar identifier"?
I guess my issue is that identifier normally means the name of a type instance....so that's a point of confusion for me at least. Jeff
