trying to require a submodule made with module* I get the following error:

require: unknown module
module name: (submod 'anonymous-module[2096977] aap)

I have tried some variations on the line marked with <---, but none of them passed. How do I refer to submodule aap?

#lang racket/base

(define x 1)

(module* aap #f
  (define a x)
  (provide a))

(module noot (submod ".." aap) ; <---
  (provide a))

(require 'noot)
a

Submodules created with module* are conceptually "after" their enclosing module; submodules created with module are conceptually "before" their enclosing module. So what you're literally attempting is not possible. You could do this:

#lang racket/base

(define x 1)

(module* aap #f
  (define a x)
  (provide a))

(module* noot racket
  (require (submod ".." aap)) ; <---
  (provide a))

However, you cannot then require that into the enclosing module.

Additionally, your use of submod is in the language position, which is probably not what you want.
