Try to imagine how to solve the second example of the sukhoi README.md using scrapy, you'll notice you'll end up with some kind of obscure logic to achieve that json structure thats outputed by the second example in sukhoi's README.md.
Also, generator expressions would make the examples more readable IMO.
self.extend((tag, QuoteMiner(self.geturl(href))) for tag, href in self.acc)
