Scalar...eTypes(3pm)

💖 Scalar::Does::MooseTypes 💖

okay bestie, so this is a manual page — it lives in the User Contributed Perl Documentation section 3pm, and its whole name is Scalar::Does::MooseTypes. Say it with me. Slay.

---

✨ NAME ✨

Scalar::Does::MooseTypes — (DEPRECATED) additional constants for Scalar::Does, inspired by the built-in Moose type constraints. like, it literally says DEPRECATED in the name section, we're not hiding that, we're leading with it 💅

---

✨ SYNOPSIS ✨

okay so here's the vibe. You bring in the constants, and you check stuff:

use 5.010;
use Scalar::Does qw(does);
use Scalar::Does::MooseTypes -all;

my $var = [];
if (does $var, ArrayRef) {
  say "It's an arrayref!";
}

the -all is doing the heavy lifting here bestie, it's pulling in every single constant for you 🫶

---

✨ STATUS ✨

This module is DEPRECATED. 😭

not me being the bearer of bad news but fr fr, use Types::Standard instead:

use 5.010;
use Scalar::Does qw(does);
use Types::Standard qw(ArrayRef);

my $var = [];
if (does $var, ArrayRef) {
  say "It's an arrayref!";
}

look at that. same energy, same result, way more current. glow up ✨
