    lowertoupper(<character|string|word>) -> <character|string|word>

This procedure converts lowercase characters to uppercase. If given a
string, every lowercase character in the string is converted to
uppercase. For example:

    lowertoupper(`a`) =>
    ** 65                         ;;; i.e. `A`

    lowertoupper('hello') =>
    ** HELLO

    lowertoupper("John") =>
    ** JOHN

If the argument is not a lowercase character, string, or word, it is
returned untouched:

    lowertoupper(`A`) =>
    ** 65

    lowertoupper([any old list]) =>
    ** [any old list]
