Good question.

  1) Pod.each { |pea| ... }. There is no indication what each will yield.
  2) In some cases, there are multiple things that can be iterated through.
      Maybe a better example:

Car.new.each_wheel { |wheel| ... }
Car.new.each_headlight { |light| ... }

Which directs me to do something like:
Car.new.wheels.each ...
Car.new.headlights.each ...

which is back to the un-encapsulation that has been previously mentioned.
