First of all if you implement #each then you should also include 
Enumerable because the expectation would be that you also have all the 
nice methods like #select, #map etc.  This makes all objects Enumerable 
which does not seem a good idea.  One drawback of this approach is that 
you won't notice if you accidentally pass something to a method which 
should be Enumerable (I mean a real collection) - or at least the issue 
might take some time to be detected.
