.IX Header "DESCRIPTION"
\&\f(CW\*(C`List::Util::XS\*(C'\fR can be used as a dependency to ensure List::Util was
installed using a C compiler and that the \s-1XS\s0 version is installed.
.PP
During installation \f(CW$List::Util::XS::VERSION\fR will be set to
\&\f(CW\*(C`undef\*(C'\fR if the \s-1XS\s0 was not compiled.
.PP
Starting with release 1.23_03, Scalar-List-Util is \fBalways\fR using
the \s-1XS\s0 implementation, but for backwards compatibility, we still
ship the \f(CW\*(C`List::Util::XS\*(C'\fR module which just loads \f(CW\*(C`List::Util\*(C'\fR.
