libclone-perl - 0.46-1+b2 main

The Clone module provides a clone() method which makes recursive copies of
nested hash, array, scalar and reference types, including tied variables and
objects.
.
It is faster (although less flexible) than Storable's dclone. Its
functionality is _not_ serializing in-memory objects (i.e. as
Data::Dumper or YAML::Dump do), but deep-copying them over to new
in-memory structures.
