      Raise up, like exit, allows you to quit pry. Instead of returning a value
      however, it raises an exception. If you don't provide the exception to be
      raised, it will use the most recent exception (in pry `_ex_`).

      When called as raise-up! (with an exclamation mark), this command raises the
      exception through any nested prys you have created by "cd"ing into objects.

      raise-up "get-me-out-of-here"

      # This is equivalent to the command above.
      raise "get-me-out-of-here"
      raise-up
