/**
* Subtype of {@link ConfigValue} representing a list value, as in JSON's
* {@code [1,2,3]} syntax.
*
* <p>
* {@code ConfigList} implements {@code java.util.List<ConfigValue>} so you can
* use it like a regular Java list. Or call {@link #unwrapped()} to unwrap the
* list elements into plain Java values.
*
* <p>
* Like all {@link ConfigValue} subtypes, {@code ConfigList} is immutable. This
* makes it threadsafe and you never have to create "defensive copies." The
* mutator methods from {@link java.util.List} all throw
* {@link java.lang.UnsupportedOperationException}.
*
* <p>
* The {@link ConfigValue#valueType} method on a list returns
* {@link ConfigValueType#LIST}.
*
* <p>
* <em>Do not implement {@code ConfigList}</em>; it should only be implemented
* by the config library. Arbitrary implementations will not work because the
* library internals assume a specific concrete implementation. Also, this
* interface is likely to grow new methods over time, so third-party
* implementations will break.
