#Split Off Ruby Hashes A little complemtent to ActiveSupport's slice. With this method you can quickly create a subhash and pass it to a method as an argument. Your original hash will contain only those keys/values that you have not split off.

gem install 'split_off'

require 'split_off'

hash = {one: 1, two: 2, three: 3, zero: nil}
hash.split_off!(:one, :two, :zero) # => {:one=>1, :two=>2}
hash # => {:three => 3}

Enjoy!
