.SH "NAME"
Function::Fallback::CoreOrPP \- Functions that use non\-core XS module but provide pure\-Perl/core fallback
.SH "VERSION"
.IX Header "VERSION"
This document describes version 0.090 of Function::Fallback::CoreOrPP (from Perl distribution Function-Fallback-CoreOrPP), released on 2020\-02\-03.
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 1
\& use Function::Fallback::CoreOrPP qw(clone unbless uniq);
\&
\& my $clone = clone({blah=>1});
\& my $unblessed = unbless($blessed_ref);
\& my @uniq  = uniq(1, 3, 2, 1, 4);  # \-> (1, 3, 2, 4)
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module provides functions that use non-core \s-1XS\s0 modules (for best speed,
reliability, feature, etc) but falls back to those that use core \s-1XS\s0 or pure-Perl
modules when the non-core \s-1XS\s0 module is not available.
.PP
This module helps when you want to bootstrap your Perl application with a
portable, dependency-free Perl script. In a vanilla Perl installation (having
only core modules), you can use App::FatPacker to include non-core pure-Perl
dependencies to your script.
.SH "FUNCTIONS"
.IX Header "FUNCTIONS"
.ie n .SS "clone($data) => $cloned"
.el .SS "clone($data) => \f(CW$cloned\fP"
.IX Subsection "clone($data) => $cloned"
Try to use Data::Clone's \f(CW\*(C`clone\*(C'\fR, but fall back to using Clone::PP's
\&\f(CW\*(C`clone\*(C'\fR.
.ie n .SS "clone_list(@data) => @data"
.el .SS "clone_list(@data) => \f(CW@data\fP"
.IX Subsection "clone_list(@data) => @data"
A shortcut for:
.PP
.Vb 1
\& return map {clone($_)} @data
.Ve
.ie n .SS "unbless($ref) => $unblessed_ref"
.el .SS "unbless($ref) => \f(CW$unblessed_ref\fP"
.IX Subsection "unbless($ref) => $unblessed_ref"
Try to use Acme::Damn's \f(CW\*(C`damn\*(C'\fR to unbless a reference but fall back to
shallow copying.
.PP
\&\s-1NOTE:\s0 \f(CW\*(C`damn()\*(C'\fR \fB\s-1MODIFIES\s0\fR the original reference. (\s-1XXX\s0 in the future an option
to clone the reference first will be provided), while shallow copying will
return a shallow copy.
.PP
\&\s-1NOTE:\s0 The shallow copy method currently only handles blessed
{scalar,array,hash}ref as those are the most common.
.ie n .SS "uniq(@ary) => @uniq_ary"
.el .SS "uniq(@ary) => \f(CW@uniq_ary\fP"
.IX Subsection "uniq(@ary) => @uniq_ary"
Try to use List::MoreUtils's \f(CW\*(C`uniq\*(C'\fR, but fall back to using slower,
pure-Perl implementation.

.SH "SEE ALSO"
.IX Header "SEE ALSO"
Clone::Any can also use multiple backends. I used to avoid it because
Storable's \f(CW\*(C`dclone\*(C'\fR (which is used as the backend) did not support Regexp
objects out of the box until version 3.08. Plus must use deparse to handle
coderefs.
