C++ isn't exactly a new language but has also had type inference for a few years. I think people still think of C++ as that dusty old thing in the corner and forget that it is actually capable of a lot of the things users of these new languages get excited about.

C++'s auto is younger than most of these languages (let alone than Haskell or MLs), to say nothing of actual tooling support.

gcc has had auto under a different name (typeof) for years and years, though i don't think it got much use outside of programming competitions.

C++11 is almost a new language. Coming back to C++ now after almost a decade away is exciting.
