Scope a variable and clean up your code with .tap

Great case for using .tap to clean up and organize code.

Example

<div class="active_messages">
  <% @active_messages.each do |message| %>
    <h1><%= message.title %></h1>
    <div class="latest_comment">
      <% message.comments.last.tap do |comment| %>
        <div class="avatar">
          <%= avatar_for(comment.creator) %>
        </div>
        Latest comment <%= time_ago_in_words(comment.created_at) %> ago by <%=    comment.creator.full_name %>
      <% end %>
    </div>
  <% end %>
</div>
