💅 Perl::...Sigils — from the User Contributed Perl Documentation girlies 🎀

okay bestie, welcome to the group chat ✨ this little page is Perl::...Sigils(3pm), and it's about to tell you why you should stop putting an ampersand in front of your function calls. yes, that ampersand. we need to talk about it. 💀

✨ NAME ✨

Perl::Critic::Policy::Subroutines::ProhibitAmpersandSigils — literally just: don't call functions with a leading ampersand sigil. that's the whole vibe. that's the assignment. 🫶

🌸 AFFILIATION 🌸

Bestie this Policy is part of the core Perl::Critic distribution — so it's not some random extra you have to go hunt down, it ships with the main character package. 👑

💖 DESCRIPTION 💖

Okay so here's the tea ☕ — since Perl 5, the ampersand sigil is completely optional when you're invoking subroutines. like, it's just out here being extra for no reason. 🙈

And it's not just a fashion choice, ngl — using it also turns off checking of subroutine prototypes. so your prototype protection is just… gone. poof. 😭

Oh and ALSO — it's easily confused with the bitwise and operator. the way that & has two whole jobs and one of them is lying to you 💀

so like, look at this:

@result = &some_function(); # not ok
@result = some_function();  # ok

see how the second one is clean, unbothered, moisturized, in its lane? 🌈 yeah. be the second one. ✨

🦋 CONFIGURATION 🦋

This Policy is not configurable except for the standard options. that's it, that's the whole section — no knobs to turn, no settings to hyperfixate on. she comes as she is 💅
