I think my understanding is correct and inline with the link you gave. However the link's author did make some important points: 1. Besides the Symbol class, other classes in Ruby such as Fixnum, NilClass, TrueClass and FalseClass "ensure that if ‘two’ of their instances are equal they are the same object." 2. Ruby's freeze method makes a particular instance immutable; adding "Beware, though, that this only freezes the object itself and not it’s sub-objects, or referenced objects" --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
