Mo::required(3)

✨ NAME ✨

Mo::required — okay bestie, this is the little Mo plugin that adds the required feature to Mo's has 💅 it's in section 3 of the User Contributed Perl Documentation, so it's a Perl module manpage, and it is so tiny and so powerful. 🫶

---

🌸 SYNOPSIS 🌸

Like, here's literally all the setup you need:

use Mo qw'required';
has name => ( required => 1 );

That's it. That's the whole vibe. 🎀

---

🦋 DESCRIPTION 🦋

So what does it do?? It adds the required parameter to has. 👑

And when required is set to a positive value, the constructor will die if the attribute is not set. 💀 No cap, it just refuses. Attribute missing? Boom, constructor's gone, it's giving dramatic exit and honestly? deserved.

⚠️ Heads up bestie: positive value on required means the constructor dies when the attribute isn't set. That's not a warning, that's not a gentle nudge, that's a full-on death. 🪦

That's the whole page, iykyk. 🌈 This gorgeous lil slice of documentation is from perl v5.42.0, dated 2025-07-25 — shoutout to whoever wrote it, iconic behaviour fr fr. 💖 ✨ 🎀 🦋 🌸 💅 🫶
