List::Util::XS(3)     User Contributed Perl Documentation    List::Util::XS(3)

NAME
       List::Util::XS - Indicate if List::Util was compiled with a C compiler
SYNOPSIS
           use List::Util::XS 1.20;
DESCRIPTION
       "List::Util::XS" can be used as a dependency to ensure List::Util was
       installed using a C compiler and that the XS version is installed.
       During installation $List::Util::XS::VERSION will be set to "undef" if
       the XS was not compiled.
       Starting with release 1.23_03, Scalar-List-Util is always using the XS
       implementation, but for backwards compatibility, we still ship the
       "List::Util::XS" module which just loads "List::Util".
