Yeesh.  An immutable singly-linked reverse-descent list?  Anyway, you're
writing code that makes it *look* like you're dealing with a mutable
object [*], and while we deal with that all the time with numbers and
strings, I think it's a Bad Idea to do that when there are true mutable
objects available.

(I doubt I'll convince you, but I can at least hope to convince other
people.  Note that you're now confusing the issue by using "list" to
refer to a structure made out of tuples.)


[*] In case anyone has lost track, the code in question is

tuple_var = (tuple_var, value)
