Message: [QUOTE="Joshua Ballanco, post: 4602094"] Not at all. Rather, this is just a subtle misunderstanding of how hash is implemented. Consider the following: => {} The only reason that Chris' example behaves like "x || x = stuff" is because he's defined a default value for the hash. If you set a default value, than you'll never have a keyed value be empty (i.e. nil). Consider further: empty => nil I think the confusion is that, in Chris' example, there's no assignment, so the hash only holds the default value temporarily (i.e. just long enough to not evaluate to nil or false).
