std::execution::just

struct just_t { /*unspecified*/ };

inline constexpr just_t just{};

execution::sender auto just( auto&&... values );

A sender factory that returns a sender which completes immediately by calling the receiver’s set_value().

Let ts be a pack of subexpressions. The expression just(ts...) is expression-equivalent to /*make-sender*/(just, /*product-type*/(ts...))
