It looks like current CVS has grown a pending deprecation warning for the update() method of Sets and that this change has been backported to the 2.3 branch. It seems to me to be bad form to add a warning in a maintenance release. The update() method was new in 2.3 and documented in the 2.3 docs. So people are going to write code using update() and then update to 2.3.1 and get warnings?

I'm also not clear on the rationale for the warning. update() seems to match the semantics of dict.update(), and it less verbose than the suggested alternative -- union_update().
