List::Util::XS(3)

✨ NAME ✨

okay bestie, welcome to List::Util::XS(3) from the User Contributed Perl Documentation — this page is literally about checking whether List::Util was compiled with a C compiler. 💅

• List::Util::XS — Indicate if List::Util was compiled with a C compiler.

🎀 SYNOPSIS 🎀

Use it like this:

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. That’s the whole vibe check it performs, no cap.

During installation $List::Util::XS::VERSION will be set to undef if the XS was not compiled. So yeah — undef in that spot is the “nope, not compiled” signal. 😭

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. iconic behavior honestly: the module is still here being a tiny compatibility icon. 👑
