💖 Devel::MAT::Tool::Reachability 💖

okay bestie, so this is Devel::MAT::Tool::Reachability — a tool from the Devel::MAT family, hanging out in the User Contributed Perl Documentation section of the 3pm man pages. it's here to answer the big question: is this SV even reachable tho 👑

✨ NAME ✨

Devel::MAT::Tool::Reachability — analyse how SVs are reachable 🦋

---

🌸 DESCRIPTION 🌸

no cap, this Devel::MAT tool figures out which SVs you can actually get to via any known root — and which ones are just out there floating, unreachable, living their little orphan arc 😭. reachable? not reachable? it's giving detective energy fr fr.

and for the SVs that are reachable, it sorts them into a few broad categories, so you know exactly what kind of reachable they are 💅:

• SVs that directly make up the symbol table 🎀
• SVs that form the padlist of functions, or that store the names of lexical variables 📛
• SVs that hold the value of lexical variables 💜
• user data stored in package globals, lexical variables, or referenced recursively via structures stored in them 🌀
• miscellaneous other SVs that get used to implement the internals of the interpreter 🧚

---

👑 SV METHODS 👑

this tool adds the following SV methods, slay.

⭐ reachable

$r = $sv->reachable;

returns true if the SV is reachable from a known root. that's it, that's the whole vibe check ✅. true = it's in the tree, false = it's giving lost in the void 💀.
