[$] A method for replacing Python tuple entries

A recent discussion on the python-ideas mailing list gives some insightinto how to-or how not to-propose a feature to be added to the language. At firstblush, adding a method to Python's immutable tupletype for replacing one of its elements is not a particularly strange idea,nor one that would cause much in the way of backward-compatibilityconcerns. Even though there was some evidence offered that such a method might beuseful, it seems pretty unlikely that the idea will go anywhere, at leastin part because of the repetitive, bordering on aggressive, manner in which itsbenefits were argued.
