title: Why isn't every type of object serializable?
body: <p>Why isn't every type of object implicitly serializable?</p>
  
  <p>In my limited understanding, are objects not simply stored on the heap and pointers to them on the stack?</p>
  
  <p>Shouldn't you be able to traverse them programatically, store them in a universal format and also be able to reconstruct them from there?</p>
