For example, the following code creates a package 'p', defines a function 'add' in it, uses the package as a module, and then exports the function.

    p = createPackage()
    p.add = function (x, y) x + y
    use(p)
    p.export("add")

    add(2, 3) ==> 5

Difference from just defining the function in a package is that the function is visible no matter what package is selected as the current package.
