Racket has a nice module system whereby a module is kept in a plain text
.rkt file. For example,
#lang racket
(provide print-cake)
; draws a cake with n candles
(define (print-cake n)
(show " ~a " n #\.)
(show " .-~a-. " n #\|)
(show " | ~a | " n #\space)
(show "---~a---" n #\-))
(define (show fmt n ch)
(printf fmt (make-string n ch))
(newline))
is in cake.rkt so that
#+begin_src scheme :session ch2
(require "cake.rkt")
(print-cake (random 30))
#+end_src
produces the actual ascii -- albeit in the *Geiser dbg* buffer (or run from
the associated REPL ch2):
; -*- geiser-scheme-implementation: racket -*-
(require "cake.rkt")
(print-cake (random 30))
=> #<void>
.......................

So, this means I can do some Racket in org-mode, but the module side has to
be outside. This seems not so elegant. Is there a babel language where the
entire ecosystem is inside Emacs/org-mode? I'd like to have the module
paradigm and have it all inside Emacs/org-mode.

It sounds like you should incorporate some tangling prior to running some
blocks so that the external files would exist when required.
The only other approach is something like a :session. I don't know if that
is setup for scheme/racket though.
