I would appreciate a review from @willingc and @gvanrossum on this.

gvanrossum

It's great to add these explicitly to the docs!

I hope you don't mind that I have tried to correct your English grammar somewhat (mostly adding or subtracting "the").

I'd also love to get @willingc's view on how to make this section have the right tone so as not to scare beginners away.
