[Nicholas Seckar] + Enumerable#first_match was like detect, but instead of returning the matching element, the yielded value returned. For example: + + user_xml = adapters(:from => User, :to => Xml).first_match do |adapter| + adapter.adapt @user + end + + But this is just as easily done with: + + user_xml = adapters(:from => User, :to => Xml).each do + break adapter.adapt(@user) + end + * Make Array#in_groups_of just return the grouped collection if a block isn't given. [Marcel Molina Jr.] * Don't destroy a HashWithIndifferentAccess if symbolize_keys! or stringify_keys! is called on it. Closes #5076.
