It's awesome that Glyph wrote this article, but so many people are getting stuck on the default names here (me too, I don't like them so very much) that it's really detracting from the commentariet.
From the Attrs documentation:
(If you don’t like the playful attr.s and attr.ib, you can also use their no-nonsense aliases attr.attributes and attr.attr).
attr.ib = "attirb" = alternate spelling of "attr"
It's too cute by half.
