NAME

       Clone::Choose - Choose appropriate clone utility

SYNOPSIS

         use Clone::Choose;

         my $data = {
             value => 42,
             href  => {
                 set   => [ 'foo', 'bar' ],
                 value => 'baz',
             },
         };

         my $cloned_data = clone $data;

         # it's also possible to use Clone::Choose and pass a clone preference
         use Clone::Choose qw(:Storable);

DESCRIPTION

       "Clone::Choose" checks several different modules which provides a "clone()" function and
       selects an appropriate one. The default preference is

         Clone
         Storable
         Clone::PP

       This list might evolve in future. Please see "EXPORTS" how to pick a particular one.

EXPORTS

       "Clone::Choose" exports "clone()" by default.

       One can explicitly import "clone" by using

         use Clone::Choose qw(clone);

       or pick a particular "clone" implementation

         use Clone::Choose qw(:Storable clone);

       The exported implementation is resolved dynamically, which means that any using module can
       either rely on the default backend preference or choose a particular one.

       It is also possible to select a particular "clone" backend by setting the environment
       variable CLONE_CHOOSE_PREFERRED_BACKEND to your preferred backend.

       This also means, an already chosen import can't be modified like

         use Clone::Choose qw(clone :Storable);

       When one seriously needs different clone implementations, our recommended way to use them
       would be:

         use Clone::Choose (); # do not import
         my ($xs_clone, $st_clone);
         { local @Clone::Choose::BACKENDS = (Clone => "clone"); $xs_clone = Clone::Choose->can("clone"); }
         { local @Clone::Choose::BACKENDS = (Storable => "dclone"); $st_clone = Clone::Choose->can("clone"); }

       Don't misinterpret recommended - modifying @Clone::Choose::BACKENDS has a lot of pitfalls
       and is unreliable beside such small examples. Do not hesitate open a request with an
       appropriate proposal for choosing implementations dynamically.

       The use of @Clone::Choose::BACKENDS is discouraged and will be deprecated as soon as
       anyone provides a better idea.

PACKAGE METHODS

   backend
       "backend" tells the caller about the dynamic chosen backend:

         use Clone::Choose;
         say Clone::Choose->backend; # Clone

       This method currently exists for debug purposes only.

   get_backends
       "get_backends" returns a list of the currently supported backends.
