Subject: [ruby-talk:20072] Ruby Style Guide

I noticed this example in the Ruby Style Guide Wiki and think it may need 
changing, but don't know where to comment on it.

I didn't want to just edit the page, because I may be talking rubbish.

  Original 

         first_name = prompt_and_read "First name"
         last_name  = prompt_and_read "Last name"
         phone      = prompt_and_read "Phone"

  Better 

        FIELDS = [ "First name", "Last name", "Phone" ]
        FIELDS.each do |prompt| ... end

I may be missing something, but I don't see how that loop can update the 
three separate variables as the original does.  It certainly makes the code 
shorter (only by one line in this case, but it could be a lot more in 
general), but doesn't seem to achieve the same effect.
