Added partial scoping to TranslationHelper#translate, so if you call translate('.foo') from the people/index.html.erb template, you'll actually be calling I18n.translate(people.index.foo) [DHH]

TimeWithZone#advance: leverage Hash#values_at and non-block form of #any? for a little less line noise, and a slight speedup (thanks raggi and Roman2K)

Time#to_s(:rfc822) uses #formatted_offset instead of unreliable and non-standard %z directive [#1899 state:resolved]

Introduce Array.wrap(foo) to wrap the argument in an array unless it's already an array. Wraps nil as an empty array. Use instead of Array(foo) and foo.to_a since they treat String as Enumerable.
