template<class C, class... Args> requires (![view](range.view#concept:view "25.4.4 Views [range.view]")<C>) constexpr auto to(Args&&... args);template<template<class...> class C, class... Args> constexpr auto to(Args&&... args);

Mandates: For the first overload,C is a cv-unqualified class type.

Returns: A range adaptor closure object ([range.adaptor.object]) fthat is a perfect forwarding call wrapper ([func.require]) with the following properties:

• Its bound argument entities bound_args consist of objects of types decay_t<Args>...direct-non-list-initialized with std​::​forward<Args>(args)..., respectively.
• Its call pattern is to<C>(r, bound_args...), where r is the argument used in a function call expression of f.
