STD::IS_LITERAL_TYPE(3)

✨ std::is_literal_type< _Tp > ✨

okay bestie, welcome to another episode of "the C++ standard library has lore" 💅 this one lives in the libstdc++ manual, and honestly? it's a short one. a little baby page. but it has DRAMA. 🎀

---

💖 NAME 💖

std::is_literal_type< _Tp > — the trait that used to ask "is this a literal type, bestie?" and now does not, because we as a community decided the question was mid. 😭

---

🦋 SYNOPSIS 🦋

#include <type_traits>

that's it. that's the whole thing. just the include. go off, header. 🌸

---

🌈 Detailed Description 🌈

here's the shape of it:

template<typename _Tp>
struct std::is_literal_type< _Tp >

and the trait is literally named "is_literal_type — yes, with that opening quote right there in the source, no cap, that's what the doc says, I'm just reporting the vibes faithfully. 💀

💜 Deprecated 💜

DEPRECATED ALERT, GIRLIES. This got marked Deprecated in C++17, and then removed in C++20. It is gone gone. If you're reaching for it in modern code, the compiler is gonna give you the side-eye. 🙈

and the reason? the docs say it plain: "The idea of a literal type isn't useful." 💀💀💀 like okay, brutal, but she said what she said. the committee woke up one day and said "not this concept being load-bearing" and it was over for her. iconic behaviour honestly 🌈

so like… don't use it. if you found this page because you were trying to use it, bestie, no you weren't. 🫶

and that's the page, babes 🎀 big thank you to libstdc++ for shipping this one out (and to Doxygen for auto-generating the whole thing from the source code, no author human required 💖), and if you see std::is_literal_type anywhere in your codebase in this, the year of our lord C++20 and beyond — it's a ghost, a memory, a vibe from a past era. 🦋 periodt. 👑✨
