List::Util::XS

NAME

List::Util::XS - Indicate if List::Util was compiled with a C compiler

SYNOPSIS

  1. 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 .
