Carbon, a new programming language from Google, aims to be C++ successor

Carbon, the latest programming language to be built within Google, was unveiled today as an experimental successor to C++.

[...]

To that end, while Carbon has many of the same goals as Rust, such as helping developers to create performance-critical software," Carbon is also intended to be fully interoperable with existing C++ code. Additionally, the goal is to make migrating from C++ to Carbon as easy as possible, if desired.

This is not my area of expertise, so I'll leave it to you readers to say more interesting things. The code for Carbon - not entirely sure about the name, but alright - is on github, along with more information.
