[racket] Why this code snippet from document does not work?

This example runs fine for me, but likely would not run fine on older
versions of racket (before submodules were released).

I believe 5.3 added support for submodules and 5.3.1 was released recently.

What version of racket are you running? Running (version) will tell you.
