Failure to process Kotlin JS/exports correctly

[nanodeath]

Hi there,

Context: I'm writing Kotlin JS, which generates a AMD-style JS module, which then gets plumbed through Rollup using rollup-plugin-amd, which in turn depends on...this.

The JS Kotlin generates initially looks like this:

define(['exports', 'kotlin'], function (_, Kotlin) {
  'use strict';
  var defineInlineFunction = Kotlin.defineInlineFunction;
  function main(args) {
  }
  _.main_kand9s$ = main;
  main([]);
  Kotlin.defineModule('my-module', _);
  return _;
});

After trickling through the build process, the final output JS is this:

var app = (function (Kotlin) {
  'use strict';

  Kotlin = Kotlin && Kotlin.hasOwnProperty('default') ? Kotlin['default'] : Kotlin;

  var defineInlineFunction = Kotlin.defineInlineFunction;
  function main(args) {
  }
  _.main_kand9s$ = main;

  return _;

}(kotlin));

Which looks fine-ish, except for one problem -- it's assuming there's a _ global when there is none. This causes JS errors when loading the page. As an immediate workaround, I'll create a "_" object on the page to absorb exports, but that seems odd to me. Thoughts?

Thanks!
