There's some precedence difference between do..end and {}, but semantically
they're the same.

Terminology and meaning are pretty much right, but I'd say there's a
reasonable difference in Ruby between "defining the method each *ON* the
Class" (emphasis mine) and defining the method each in the Class, on the
instance. But that's being picky: you knew what you meant, and so did I. 

(In case that was unclear, you could define the method "on the class
addressbook" with def AddressBook.each(); ...; end). If thats still unclear,
ignore the whole last 2 paragraphs.
