std::experi..._tagged_pair(3)

okay so welcome to the std::experi..._tagged_pair(3) page from the C++ Standard Libary manual 💅 this one is short and cute, but every detail still matters, bestie.

🌸 NAME 🌸

std::experimental::ranges::make_tagged_pair — std::experimental::ranges::make_tagged_pair

Yes, it literally says it twice. Iconic behavior. 🎀

✨ Synopsis ✨

Defined in header <experimental/ranges/utility>.

template< TagSpecifier Tag1, TagSpecifier Tag2, class T1, class T2 >
constexpr ranges::tagged</*see below*/, Tag1, Tag2> make_tagged_pair(
(ranges TS)
T1&& x, T2&& y );

So this is the ranges TS situation, and it's the convenience function for creating a tagged pair. It deduces the element types from the arguments, but the tag specifiers must be explicitly specified — no sneaky auto-deduction for those, iykyk. 🦋

The /*see below*/ part of the return type is literally:

decltype(std::make_pair(std::forward<T1>(x), std::forward<T2>(y)))

That's the whole "see below" mystery. Slay. 🔥

💖 Return value 💖

It returns R(std::forward<T1>(x), std::forward<T2>(y)), where R is the return type. That's the return-value moment, no cap. ✨
