At least you can implement things like vector in C++. I challenge anyone to write the same for C macros. (this is semi-serious - if you get a full generic STL for C that is usable that would prevent a large number of bugs. The implementation can be as bad as you want, so long as the user API is not too difficult. Though note that I'm not a C programmer and so if there are better ways someone else is doing this I'm not aware of it)
