;;Replaced with the following:
(module run2 mzscheme
  (require "struct.ss"
           (planet "namespace.ss" ("schematics" "namespace.plt" 1 0)))

  (let ((ns (make-namespace 'initial))) ;based on example in 
    (namespace-attach/require           ;doc.txt for namespace.plt
     ns
     "struct.ss")
    (with-namespace
     ns
     (read-eval-print-loop))))
;; compiled with mzc -v --exe run2 run2.ss

;;And when I run it:
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
~/tmp/modtest $ run2
namespace-attach-module: module not instantiated
(in the source namespace): |,/home/joel/tmp/modtest/struct|

 === context ===
namespace.ss:116:2: namespace-attach/require
#f::353: loop
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Now, how do I *instantiate* the module?  Is there more to it than
require?

Thanks,
Joel
