       "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".
