Interesting language - its syntax looks like a mix of Rust and Go, with a few of its own idiosyncrasies to distinguish it from those languages.

> Carbon is a concentrated experimental effort to develop tooling that will facilitate automated large-scale long-term migrations of existing C++ code to a modern, well-annotated programming language with a modern, transparent process of evolution and governance model.

This is probably where Go and Rust fail to be C/C++ "successor" languages, as interop between those languages doesn't seem to be as seamless as Carbon aims to be.

Will keep an eye on its development!
