title: How do I test if all items in an array are identical?
body: <p>I can generate a few lines of code that will do this but I'm wondering if there's a nice clean Rubyesque way of doing this. In case I haven't been clear, what I'm looking for is an array method that will return true if given (say) <code>[3,3,3,3,3]</code> or <code>["rabbits","rabbits","rabbits"]</code> but will return false with <code>[1,2,3,4,5]</code> or <code>["rabbits","rabbits","hares"]</code>.</p>
  
  <p>Thanks</p>
