I have been coding in straight C lately on an embedded personal project and have loved it immensely. I know what is going on and have a good shot at predicting the resulting assembly.

However, for me, C falls down on large projects. I know there a lot of hate on objects lately, but the complexity of a project decreases while the maintainability increases when you use properly designed interfaces. You “force” the new guy to do it right because the interface makes it obvious. I know there are ways to enforce encapsulation with C, but I’ve never worked on a (large) codebase where this has been successful.
