Subject: Cloning into an object

Anybody know how to generically copy (shallow like clone) an
object into another object?  It would be nice to handle the
case where the objects have a different class, but I would at
least like to know how to do it when the classes are the same.

Here is an example of what I would like to do:

dest = Object.new # or String.new if necessary
source = "hello world"
destid = dest.id

source.clone_into(dest)

dest             -> "hello world"
dest.id==destid  -> true
dest.class       -> String
