changes = old_ssos.zip new_ssos

update_sso = Proc.new do |old, new|
  u = User.find_by_sso_id(old)
  u.sso_id = new if u
  u.save! if u
end
=> #<Proc:0x0c651ccc@(irb):36>

changes.each do | old, new|
  update_sso.call(old,new)
end

Like my other best selections, I like this because it represents a change in my thinking. This is the first time I used enumerable.zip and Proc.new in this manner. I like that I approached this problem using the functional elements in Ruby.
