Perl::...minator(3pm)

✨ NAME ✨

okay bestie, the manual name up top is Perl::...minator(3pm), and it's from the User Contributed Perl Documentation girlies 💖. The actual NAME is Perl::Critic::Policy::ValuesAndExpressions::RequireUpperCaseHeredocTerminator — say that three times fast, I dare you 😭 — and it's literally about writing " <<'THE_END'; " instead of " <<'theEnd'; ". periodt 💅.

🦋 AFFILIATION 🦋

This Policy is part of the core Perl::Critic distribution. slay ✨.

---

🎀 DESCRIPTION 🎀

okay so for legibility, HEREDOC terminators should be all UPPER CASE letters (and numbers), without any whitespace. Conway also recommends using a standard prefix like END_ but this policy doesn't enforce that. ngl, it's giving "keep it readable, bestie" 🌸.

Here's the exact vibe check from the page — not-ok first, then the iconic ok version:

  print <<'the End';  #not ok
  Hello World
  the End

  print <<'THE_END';  #ok
  Hello World
  THE_END

🚨 not me pointing at the #not ok example like it's the villain of the group chat 💀.

💜 CONFIGURATION 💜

This Policy is not configurable except for the standard options. that's it, that's the tea ☕ — no extra knobs, no secret settings, just standard-options energy 🫶.
