You appear to be correct, but it strikes me as really odd that
(a) In a language which prides itself on metaprogramming, the interpreter
namespace needs to be manually bootstrapped with a specific module.
(b) That the form the error takes is not an error with the requires/provides in
the `main.rkt` for my #lang, but as an error in a module which is using it.
This code:
|#lang racket
|(require "Value-Forms.rkt"
| "Operator-Forms.rkt"
| "Variable-Forms.rkt")
|
|(provide
| #%module-begin
| #%top-interaction
| #%datum
| #%app
| (all-from-out "Value-Forms.rkt"
| "Operator-Forms.rkt"
| "Variable-Forms.rkt"))
Should definitely complain if its imports aren't available.

Relatedly, even if `main.rkt` and `lang/reader.rkt` are independent, it's
really odd that my module beginning with `#lang racket` is insufficient for
raco to pick up the racket dependencies.

Thanks, I'll think some more about this.

This appears to be precisely the necessary set of minimum ++libs. It *really*
ought to be documented somewhere, in big bold letters.
Thanks for the help!
