### execution::can_execute

A type trait that determines whether a `execute` expression is well-formed.

    template<
        typename T,
        typename F>
    struct can_execute

Class template `can_execute` is a trait that is derived from `true_type` if the expression `execution::execute(std::declval<T>(), std::declval<F>())` is well formed; otherwise `false_type`.
