There are various modules offering a "clone" routine, even in core.
But the question is tricky because details are important if blessed objects ° are involved or speed matters.
In the end you need to know what you really want.
Update
°) To be more specific how do you clone an arbitrary object "correctly" if the class doesn't provide a clone method?
And what is "correctly" and "good enough" ? :)
Update
For instance an array @bus containing objects of persons sitting in a bus like say $Rolf and $MrSnrub.
After copying the bus, it'll depend on the application if you really want to clone the persons too.
I'd consider creating a clone of person highly unwanted. Especially identity theft of $Rolf. ;)
If I'm the passenger in two different busses, you'd want to update personal information like addresses only once...
