Those 4 lines in a REPL produce 43, but my guess is that you have the
code in a module.

In a module, you'll need to manage the namespace more explicitly (or
maybe reflection won't be the way to go after all).

See

  http://docs.racket-lang.org/guide/reflection.html

for more information about namespaces.
