code: def lazy_load_stub_paste():
      """
      A stub function for paste(), which will load the real paste() function when
      called so that the real paste() function is used for later calls.
  
      This allows users to import pyperclip without having determine_clipboard()
      automatically run, which will automatically select a clipboard mechanism.
      This could be a problem if it selects, say, the memory-heavy PyQt4 module
      but the user was just going to immediately call set_clipboard() to use a
      different clipboard mechanism.
  
      The lazy loading this stub function implements gives the user a chance to
      call set_clipboard() to pick another clipboard mechanism. Or, if the user
      simply calls copy() or paste() without calling set_clipboard() first,
      will fall back on whatever clipboard mechanism that determine_clipboard()
      automatically chooses.
