Why do you think that shouldn't matter?

In fact, nothing matters more.

Nowhere, unless you store it somewhere.

I think the need to do this shows some design problem. See augmentPage
method in pristine project - it sets up callbacks that need to do things
for a Myapp instance without actual need to publish it. I think the call
to doNextTrack is also needed more-or-less as a reaction to some event
(broad meaning of a word), which should be also done by Smalltalk
installing the callback itself to appropriate place (not trying to get
in from JS side). Ideally, the Myapp._start() call should be only use of
globals and the pieces of an app can then talk to each other (import
vars FTW).
