# 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` .
