 I'm afraid that this won't have as much impact as you think, as most of
 the modules will be imported anyway during startup:

  * because they are used anyway before the window is brought up,
  * because some other module not in our codebase imports it eagerly.

 But I would love to be _proved_ wrong ;)

 so that the sugar folks can keep their 'all imports must be at the top of
 the file' coding guidelines without killing our performance.

 As I said somewhere else, if someone can provide a patch that improves
 user perceivable performance measurably by just shuffling imports around,
 I don't think that any style guideline will get in the way.
