Agreed. Maybe add immutability with copy semantics by default. And no null (through enumerations but worth pointing out).

Most of the Rust debates, praise and criticism are about higher level features, but just these sane pleasurable fundamentals is the main thing I miss in most languages (mostly Go and JS in my case).

I get it, the Rust enum system is such a connivence, but well the secret sauce in the readme is what the "official people" say....
