That would be Chez Scheme [0], maintained actively by Cisco, a company that you may have heard of - who also use the language extensively.

Racket is porting to using Chez, because it is the industry standard, it's performant, and rock solid.

The GNU alternative to Chez is Guile. Emacs can run with Guile, and Guix is built on it. It's got a fairly large community.

Outside of Chez and Guile, there are implementations and communities, but comparatively, they're tiny. Those two are the only big names you need. Like GCC and Clang for C. There are other C compilers. But you only need to know those two.

I think it already happened in 8.0

Thanks. I'm going to install guile and tinker around with it! So far it looks pretty good.
