>From the manual

        The new primitives that you add to Guile with
        `gh_new_procedure' or
        with any of the other mechanisms are normally placed into the
        same
        module as all the other builtin procedures (like `display').
        However,
        it is also possible to put new primitives into their own
        module.

Apart from the outdated reference to gh_new_procedure, this is wrong.
boot-9.scm drops you into the guile-user module, while builtins are in
the guile module.

I suggest that this be documented more prominently, I spent more than
1.5 hours figuring oupt why the attached program didn't work. Also
note that the scheme code (in vain) tries to import the guile and
guile-user modules.  Finally, I'd suggest that the chapter containing
the above doc snippet be linked from "Modules" section.

One final nitpick: it would be nice to have docstrings for the
procedures in ice-9; specifically, all the glorious comments in
ice-9/boot-9.scm are not available from the internal help facilities.
Is there some kind of reason for that, or can I submit a patch?
