A lot of people use #each this way in Ruby, yes, but I don't think it's usually justified. #each is primarily designed to handle side effects. "Do stuff to item" is usually better accomplished with a chain of #map, #select, #inject, #grep, etc. If "do stuff to item" is a multiline set of steps, sure you can use #each. I prefer, though, to abstract that set of steps into a lambda or named function and then map the function onto each item. Then again, I'm biased. I really like Ruby for its higher-order Lispiness, and not for its webbiness.
