Not really a "language" but an implementation of the Scheme programming language.

IIRC, the whole point of renaming it Racket is to show that PLT Scheme is "more than just scheme".

I realize that, but it would be false to call it a "language"; it's more appropriate to call it an "environment".

Or rather, to show that it's not just R6RS Scheme.

My impression is that it goes way far and beyond the scheme standard with all its additional features.
