In constructive: Display Idiomatic Code to Construct Most R Objects

#' Constructive options for class 'clock_naive_time'
#'
#' These options will be used on objects of class 'clock_naive_time'.
#'
#' Depending on `constructor`, we construct the object as follows:
#' * `"as_naive_time"` (default): We build the object using `clock::as_naive_time()`
#'   on a `clock::year_month_day()` call of the same precision.
#' * `"next"` : Use the constructor for the next supported class.
#' * `"list"` : We define as a list and repair attributes.
#'
#' @param constructor String. Name of the function used to construct the object, see Details section.
#' @inheritParams opts_atomic
#' @return An object of class <constructive_options/constructive_options_clock_naive_time>
