I've learned some Racket, and can comfortably program in it, but I only learned it as an ordinary language, much like Scheme. I know Racket is much more than that, for its "language-oriented" features. Languages become a first-class member in Racket, and to my understanding, even "#lang racket" is just a language built on some core. What I want to know is, what's the very core of Racket?
I've noticed that in the Racket Reference there is a section "Fully Expanded Programs", which seems the very core of Racket. But it still takes an S-expression form, and apparently Racket allows language customization on the syntax level. I wonder if the S-expression language is the core of Racket, or the entire Racket has a different structure? I would really appreciate it if anyone could explain it in a simple way or could point out some good (and short) material for me to read. The Racket Reference is too long, and I believe the core Racket can be well explained in a much shorter piece of text, if I just look for a brief understanding. Also my question may be confusing, because I don't understand Racket well at all. Feel free to correct me or ask for clarification.
