    Go has GC and Rust doesn't. If you were to design an explicitly C-like language with memory safety and without GC, it would look a lot more like Rust than Go. The idea that Rust was designed by a bunch of C++ fans is absurd. Most of us were ML fans more than anything.https://twitter.com/Pessimizations/status/1154473316952023040 …

    Do you disagree with it? I'm curious to know why, it seems more or less accurate to me.

        From a memory management perspective, Go doesn't look like anything like C. But from the perspective of a language which in 2019 refuses to add generics, it is kind of reminiscent of C (to me at least).

        The issue is that generics are basically a requirement for memory safety without GC as Rust does it. Otherwise you can't create safe abstractions, which would mean that every time you want a linked list you have to write unsafe code. That would undermine memory safety.

        Honestly the *concept* of C++ fans is absurd, but apparently they do exist. Each to their own I guess, as long as they're all consenting adults and don't do it near my kids.

        Hey now. C++ is fine, and Rust uses a lot of its philosophy (RAII, zero-cost abstractions, etc)

        Yeah but "GC" contains "C".

        The closest language to Go is ML, particularly Reppy's Concurrent ML. So ML is actually the link between Rust and Go. IMHO 🤓
