init() order might be different from other build systems #6

JS code from the same Go code both with and without minimizing worked on my local machine (I have confirmed gopherjs serve --tags=example -m). Is there a good way to debug this? Now it's hard since the js code is minimized.

I'll have to investigate this. As far as I know I haven't changed the actual init code. My bootstrap code runs before the init - gets all the packages loaded and calls the $mainPkg.$init just like GopherJS.
