A DESCRIPTION OF THE PROBLEM :
java.util.Map has 10 'of' convenience methods for instantiating Maps. Example:

Map<String,Integer> map = Map.of("H", 1, "C", 6, "N", 7, "O", 8);

In some cases, users may wish to obtain values in order. It'd be nice if SequencedMap had its own 'of' methods for this purpose.
