There is little of interest in "object-oriented" languages; very little of the benefit of coding in C++ (vs C) arises from object support in the language, and very little from syntactic convenience. If that were all, there would be hardly any point to switching.

It is about putting the type system to work performing logic at compile time, to generate code that is correct by construction. This is not something exotic; it is daily life for a C++ programmer.

Alas, this paradigm of C++ programming is a relatively modern concept, which relies heavily on language features introduced in C++11 and more recently. Most C++ projects I've worked on in my career use C++ as "C plus classes", and the use of types-as-compile-time-assertions was a controversially innovative suggestion. It must be nice to work in an environment where this sort of "types for compile-time logic" approach is commonplace. :-)

It really is.

MongoDB's core server engineering organization is very well-run. (And is hiring.) We are using C++14 for the current release, probably C++17 in the next.
