Isn't that just Go? They always had their own standard library (which they would never update to use newer syscalls).

Parts of Go's runtime are written in C, so the end-to-end being single-language is emphatically not like Go. relibc is a genuine libc implementation. However, I do believe Rust on Redox might indeed not factor through relibc's C interface for everything, taking advantage of Rust being on both sides. That is like Go.

ldd tells me go depends on libc and libpthread (at least on linux), so it still needs c code at runtime.

  All you have to do is build the toolchain with CGO_ENABLED=0. The optional CGo bits are not needed for anything that the compiler cares about I don’t think; IIRC with CGo enabled it will use the system’s DNS resolver on Linux for example, instead of reading resolv.conf and talking to DNS servers directly.
