[racket] Module runs fine, but won't scribble

I tried it just now (changed the #lang of the scrbl file), and nope,
scribble still gave the same error message. The call trace blames
include-exported. My module begins with

#lang at-exp racket/base

which is copied (along with many other stuffs) from the module file/gif
as suggested by the 'In-source Documentation' part of the scribble user
guide.

I managed to make a minimal example (attached). Hope this help
pinpointing the problem. (I should've thought about it earlier, duh...)

I think the problem is "Scribble In-source Documentation fails if the
documented module shadows a symbol from its #lang". (Did I say it
correctly?)

I'd say that if I were an old grandpa trying to cross the road and that
guide were a young boy, then he helped me until the middle of the road
and then ran away.
