Because that's not how "each" works. You cannot call a method on "each" 
in order to call it on every element. The "each" method without a block 
returns an Enumerator.

So you'll either have to stick with the solution above or write your own 
method. Or you should rethink the structure of your data. A deeply 
nested hash or array is almost always bad design and should be replaced 
with with an appropriate object (like a table, a tree or whatever fits 
best).
