For example, the following code contains a template expression that uses the
template processor `RAW`, which simply yields the `StringTemplate` passed to it:
int x = 10;
int y = 20;
StringTemplate st = RAW."\{x} + \{y} = \{x + y}";
List<String> fragments = st.fragments();
List<Object> values = st.values();
`fragments` will be equivalent to `List.of(" + ", " = ")` and `values` will be
the equivalent of `List.of(10, 20, 30)`.

To preserve the semantics of string templates and text block templates, the
list returned by `fragments()` must be one element larger than the list
returned by `values()`.
And yet, in the example given above, the list of fragments List.of(" + ", " =
") is one element smaller than the list of values List.of(10, 20, 30). The
example is wrong. It’s worth a note in the doc that if an interpolated
expression begins and/or ends the template, there will be a zero length
fragment at the beginning or end of the fragments list.
