Actually, this is a bit stupid.  It doesn't seem like a good idea to
be able to walk around the modules just because most of them happen to
provide a primitive for walking around modules.  Walking into the R5RS
module would be like cutting the branch you're sitting on.  :)

A more reasonable solution is to put such abilities into the repl
itself.  Scheme48 solved it by having special repl commands beginning
with a comma.  RScheme adopted this approach too.
