-Builds upon and enhances `#to_sentence` further by answering a sentence which all elements are inspected -- where each element of the array is called with `#inspect` -- before turned into a sentence using `"and"` as the default conjunction and `", "` as the default delimiter. This is useful when providing detailed error messages _and_ you need to detail the types of element used.
