Class::Can(3pm)

💖 Class::Can — the manual page, but make it make sense 💖

okay so bestie, you know how you're staring at a class like "what can you even do??" and nobody's telling you anything?? yeah. that's what this is for. Class::Can is that friend who knows everyone's business and will absolutely tell you. ✨

---

✨ NAME ✨

Class::Can — peek inside a class/method and find out what it can do (and, like, why it can do it) 🕵️♀️💅

---

🌸 SYNOPSIS 🌸

the whole vibe in one little code block, no notes:

use Class::Can;
print Dumper { Class::Can->interrogate( 'Class::Can' ) };
__END__
$VAR1 = {
          'interrogate' => 'Class::Can'
};

see how Class::Can interrogated itself and the answer was just... interrogate → Class::Can?? that's not a bug that's a serve 🫶 iconic honestly

---

🦋 DESCRIPTION 🦋

so here's the tea ☕: Class::Can goes and interrogates the object heirarchy of a package — yes, it walks the whole family tree, the whole ancestry situation, main character energy — and hands you back a hash.

and what's in that hash?? listen:

• the key is each method the class could dispatch — like, every method it might end up calling 👑
• the value is the package it found it in — so you know exactly where that method was living this whole time 🏠

basically: what it can do, and which package is claiming credit for it. no cap. 💯
