There is one difference: I created a class while the other example
uses nested Hashes.  Frankly, since with Ruby it is so easy to create
classes, I do not understand why people go about to suggest creating
nested structures of Hash and Array combinations.  Look at this
example:

It shows quite obviously that there are "things" which always have a
"menu" (or rather a name) and an "action".  Why then not just create a
class for that?

Thing = Struct.new :menu, :action

etc.
