The "closure" chapter is a stub

I think it'll be better to wait until the closure reform lands, before extending it.

I think the official tutorial does a much better job with closure explanation here. I found closures very confusing and I fixed a lot of the tutorial closure section asking lots and lots of IRC people questions.

Actually, I think your closure section makes a lot of sense but only because I already understand closures somewhat.
