#lang racket/load and (load PATH) are less idiomatic and more
low-level in Racket. I don't know how did racket/load and load
interact with ``raco exe'' but here's another way to make it work.
Everything is placed inside modules.
$ racket test.rkt
... ok ...
$ raco exe ++lib racket/base/lang/reader test.rkt
$ ./test
... ok ...
;; include.rkt
#lang racket/base
(provide new-config)
(define new-config "new-value")
;; test.rkt
#lang racket/base
(require racket/runtime-path
;; (for-syntax racket/base) is for expansion-time
;; evaluation in define-runtime-path
(for-syntax racket/base))
(define *CHANGED-STRING* "old")
(define-namespace-anchor a)
(define ns (namespace-anchor->namespace a))
(define-runtime-path
inc-path (string->path "include.rkt"))
(define (load-rc)
(parameterize ([current-namespace ns])
(set! *CHANGED-STRING* (dynamic-require inc-path 'new-config))))
(load-rc)
(printf "~A~%" *CHANGED-STRING*)
