std::experi...TagSpecifier(3)

💖 NAME 💖

From the C++ Standard Libary manual (yep, that spelling is canon here) — page std::experi...TagSpecifier(3):

std::experimental::ranges::TagSpecifier — std::experimental::ranges::TagSpecifier

That's literally the NAME section doing its little twin thing. Iconic.

📜 Synopsis 📜

Defined in header <experimental/ranges/utility>
template< class T >                                        (ranges TS)
concept bool TagSpecifier = /* implementation-defined */;

Okay so TagSpecifier<T> is satisfied if and only if T is a tag specifier for use with ranges::tagged. That's the whole vibe check, no cap.

The Ranges TS provides a set of tag specifiers in <experimental/ranges/algorithm>. And bestie, listen: users cannot define their own tag specifiers. Periodt. 🫶
