The problem with C++ error messages is that the compiler isn't told enough about the library programmer's intentions for it to explain usage problems to users of the library. A new feature of C++09, due out next year, called "concepts", will enable library writers to tell the compiler enough so it can produce short, helpful error messages for mistakes in calls to the library.

I keep wondering why they called it concepts instead of interfaces?

It's a term from the STL, which predates Java, where it's not an interface
so much as a set of behavioral guarantees: I'm fairly sure that a Java
interface couldn't express what an STL concept can. (Now I will shut up
and let ncm, an actual C++ expert rather than a poseur like me, tell me
I'm full of crap. I expect I am.)
