module export corner case

[jfirebaugh]

What structure should the following generate?

    /** @module mod */
    /** foo */
    module.exports = 1;

That's actually a case of a multiply defined symbol (#176). Correct documentation would be:

/** @module {number} mod */
module.exports = 1;

And this should result in a comment with @name mod, @kind module, and no @memberof.
