[racket] eval, namespaces, and the REPL

More specifically, I think section 15.1.2 of the guide addresses exactly
what you want to know. More specifically:

/quote

  #lang racket

  (eval '(cons 1 2))

This fails because the initial current namespace is empty. When you run
racket in interactive mode (see Interactive Mode), the initial namespace
is initialized with the exports of the racket module, but when you run a
module directly, the initial namespace starts empty.

/endquote
