Same with lighting candles if you’re actually going to be using the light immediately.
This was my first reaction when I read mik5’s post.
But if you read it again you will notice that the point is that since we don’t fully understand bein hash’mashos, the day can switch from one to the next at any moment. This means that even if you light candles in order to use the light immediately, that “immediately” might already be the next day.
My problem is, by that logic, it should have nothing to do with melocha. For example, I shouldn’t be allowed to move a chair across the room to sit on it immediately because by the time I sit on it it might be the next day.
