As with other varargs method calls, it is possible to pass an array with the values.
I think it would be useful to describe the arguments as using the varargs nomenclature and indicate
the values are in the array.  For example, the `java.util.List.of(E... elements)` method is explicit 
about the array. Anther API using varargs EnumSet.
