You call the function that the object provides for this purpose, if any. The ability to clone an object is not special in Perl; it is treated just like any other method. Perl doesn't provide a clone method for you automatically; if you want one in your own objects, you have to write it yourself. If you want to clone an object from a library provided by someone else, you have to read its documentation and find a clone object. Not all functions provide a clone function; it may not be possible or desirable to clone a given object. Consider for example an object which owns a network socket: if you were able to clone the object, you could create two different objects which own the same socket; this is a Bad Thing.
