okay bestie so this is ops — a Perl pragma, and its whole entire job is to restrict unsafe operations when compiling 💅 like it's the bouncer at the club door of your compiler, checking IDs, no cap.

✨ NAME ✨

ops — Perl pragma to restrict unsafe operations when compiling 🦋

---

🌸 SYNOPSIS 🌸

perl -Mops=:default ...    # only allow reasonably safe operations

perl -M-ops=system ...     # disable the 'system' opcode

like. look at those little one-liners go 😭 so cute, so powerful.

💖 DESCRIPTION 💖

okay so here's the tea 🫖 and it's important tea, so listen up:

The ops pragma currently has an irreversible global effect. like, irreversible. no take-backs. not me making a decision you can't undo 🙈

and because of that whole situation, it's only of significant practical use with the -M option on the command line — i.e. pass it at perl startup, on the command line, and let it do its thing from the jump. that's its moment, that's its main character energy ✨

if you wanna actually understand opcodes, optags, opmasks, and — critically — the important info about safety, go read the Opcode module. fr fr, that's where the lore lives 📖
