I would say in this case it is, because all the extra stuff is just 
verbiage. It obscures the algorithm you're actually interested in, which is 
to make a new list where each element is the old list with 'bar' applied to 
it. All the stuff with the iterator and the types and all is just junk you 
have to repeat wherever you need to do this.
