title: Print all objects in a workspace
body: <p>I cannot find out how to list and print all objects in a workspace. I'd like to see them all and understand what's going on. For example, <code>ls()</code> gives you 30 objects. How, besides typing them individually, is it possible to display them all. Seems so trivial, the solution will probably quite embarrasing. The closest I've come was <code>ls.str()</code> and the idea of looping over the objects.</p>
  
  <p><strong>Edit</strong>: <em>This is not for data frames. I have a workspace full of functions, without data, and like to understand which ones reference which etc.</em></p>
