🦋 Perl::...onstant(3pm) — bestie edition 🦋

✨ NAME ✨

TooMuchCode::ProhibitUnusedConstant — bestie, it finds unused constants. that's it. that's the whole vibe. 🎀

---

🌸 DESCRIPTION 🌸

so here's the tea ☕ — this policy goes on a lil detective mission and finds your constant declarations made with the constant pragma, and then it goes looking to see if those constants actually show up anywhere else in the rest of the code.

heads up bestie: the scope of searching is within the same file. it does not follow you across files. no cap. 🫶

it recognizes constants defined in two simple forms, and here they are, literally verbatim, i'm not touching them:

use constant PI => 3.14;

...and then also this iconic little multi-constant moment:

use constant { PI => 3.14, TAU => 6.28 };

that's the whole thing. two forms. it knows them. it finds them. it tells you when nobody's using them. main character energy fr fr. 👑
