Hrm.  Even when it's something that's supposed to be immutable?  I'm
asking because I'm currently using a tuple for the digit list in my BCD
module, and I'd like a clearer explanation of why you think that it
should be a list (assuming you do).

I'm only using a tuple for efficiency of storing numbers instead of
characters.
