Although one major problem I have with using # to hide setup code, is that the sphinx won't respect the leading # and still renders the whole block, which leading huge chunk of ugly code blocks.. What do you recommend to addressing it?

Same comment left here.

Yeah, what I hope we can do is find some way to add a sphinx plugin or something to avoid rendering the blocks of ugly code. We can maybe do this as a follow on PR / issue.

I will file a ticket for it
