+        # FIXME: Updating a cell's value should be able tochange the cell's type,
+        #        but that isn't currently possible. This will cause weird bugs
+        #        when one changes the value of a Number cell to a String. e.g.
+        #
+        #           cell = Cell::Number(*args)
+        #           cell.value = 'Hello'
+        #           cell.formatted_value # => Some unexpected value
+        #
+        #        Here are two possible solutions to such issues:
+        #        1. Don't allow a cell's value to be updated. Use a method like
+        #          `Sheet.update_cell` instead. The simple solution.
+        #        2. When `cell.value = ` is called, use injection to try and
+        #           change the type of cell on the fly. But deciding what type
+        #           of value to pass to `cell.value=`. isn't always obvious. e.g.
+        #           `cell.value = Time.now` should convert a cell to a DateTime,
+        #           not a Time cell. Time cells would be hard to recognize because
+        #           they are integers. This approach would require a significant
+        #           change to the code as written. The complex solution.
+        #
+        #        If the first solution is used, then this method should be
