Maybe a better way to phrase this is, while counting may be what 
you're implementation needs, it is not immediately obvious what 
'i' should be. Someone who desires an index into the original 
array will expect 'i' to be that; even though it can be explained 
that .take() is not the same range as the original.

Thus it is better to be explicit with the .enumerate function.
