In addition to initializing the namespace, you need to set
printer-related parameters in the evaluator.

We're in the process of putting all the relevant settings for student
languages in one place. It's currently in `htdp/bsl/runtime' as
parameterized over options for a specific student language, where each
`htdp/Xsl/reader' provides the options for a given language. So, set up
`the-eval' like this:

  (lambda () ((dynamic-require 'htdp/bsl/runtime 'configure)
              (dynamic-require 'htdp/isl/lang/reader 'options))))
