Import file into an IIFE in JavaScript

Question

Is it possible to import files into an IIFE block in Javascript just like you do with the RequireJS? I.e. is it possible to do the following:

define([
    '/path/to/some/file'
], function (importedFile)
{
    /* Now use imported file */

    importFile.awesomeStuff();
});

But with IIFE?
