If Python wanted to encourage method-chaining-style, then list.sort(),
list.reverse(), and several other built-in type methods would (ala
Ruby) return self rather than None. Since they don't, and since
"uncommon idiom" is a near-oxymoron, I think we can safely conclude
that method chaining isn't idiomatic in Python. Not that it doesn't
have specialized uses though (See asterisk note).
