Jim already caught and fixed the list examples in the latest javadoc, 
which says:

fragments will be equivalent to List.of("", " + ", " = ", "") and values 
will be the equivalent of List.of(10, 20, 30).

I agree that the javadoc should flag the existence of zero-length 
fragments; my later mail offered text for `fragments()` and `values()` 
which did so; that offering should be treated as merely the first draft 
of how to explain the reification of a source-code template.
