This lesson is problematic, as it encourages a major ruby anti-pattern :(, namely, using conditionals such as if or unless inside of an iterator rather than using the built-in enumerables. While I realize it is intended as a gentle introduction, perhaps a lesson which does not include an iterator would be preferable?
