// The reason why these lines are necessary is the fact that Java is ambiguous. There are cases where the
// sequence of characters ">>>" and ">>" should be recognized as the single tokens ">>>" and ">>". In other
// cases however we want to split those characters in single GT tokens (">").
//
// For example, in expressions ">>" and ">>>" are valid, while when defining types we could have this:
//
// List<List<Set<String>>>>
//
// You can see that the sequence ">>>>" should be interpreted as four consecutive ">" tokens closing a type
// parameter list.
//
// The JavaCC handle this case by first recognizing always the longest token, and then depending on the context
// putting back the unused chars in the stream. However in those cases the token provided is invalid: it has an
// image corresponding to the text originally recognized, without considering that after some characters could
// have been put back into the stream.
//
// So in the case of:
//
// List<List<Set<String>>>>
// ___ -> recognized as ">>>", then ">>" put back in the stream but Token(type=GT, image=">>>") passed to this
// class
// ___ -> recognized as ">>>", then ">>" put back in the stream but Token(type=GT, image=">>>") passed to this
// class
// __ -> recognized as ">>", then ">" put back in the stream but Token(type=GT, image=">>") passed to this
// class
// _ -> Token(type=GT, image=">") good!

// So given the image could be wrong but the type is correct, we look at the type of the token and we fix
// the image. Everybody is happy and we can keep this horrible thing as our little secret.

* A definition of a record.<br>
* {@code record X(...) { ... }}

* Note that the syntax of records is substantively different to standard classes/interfaces/enums. Specifically, note
* that record header contains the component declarations - where a "component" is defined as a non-static field.
* </p><p>
* This is in contrast to "normal" classes, where fields declarations are within the class body (optionally then
* initialised
* within a constructor.
* </p><p>
* Also note that the constructor for records does not accept any parameters.
* </p>
*
* <p>
* Consider this example from https://openjdk.java.net/jeps/359
* <pre>{@code
* record Range(int lo, int hi) {
* public Range {
* if (lo > hi)
* throw new IllegalArgumentException(String.format("(%d,%d)",lo,hi));

/**
* <h1>The instanceof statement</h1>
*
* <h2>Java ?? to 13</h2>
* The {@code instanceof} expression is a
* <a href="https://docs.oracle.com/javase/specs/jls/se11/html/jls-15.html#jls-15.20">relational operator</a>,
* evaluating to true if the object on the left hand side
* is an instance of the type ({@link ReferenceType}) on the right hand side.
* <br>
* <br>
* Example:
* <br>{@code tool instanceof Drill}
* <br>
* <br>This is then used wherever a conditional/boolean value can be used. For example:
* <br>
* <pre>{@code if (obj instanceof String) {
* String s = (String) obj;
* // use s
* }}</pre>
* <br>
* <h2>Java 14</h2>
* Since JDK14, it is possible to bind a variable that is cast to the type being tested against.
* This is referred to as a {@code Pattern} within <a href="https://bugs.openjdk.java.net/browse/JDK-8181287">JEP305</a>,
* and avoids the need to cast to the desired type.
* <br>
* Example:
* <br>{@code tool instanceof Drill d}
* <br>
* <br>This is then used wherever a conditional/boolean value can be used. The scope of the variable created can vary, and is defined further within
* <a href="https://bugs.openjdk.java.net/browse/JDK-8181287">JEP305</a>.
* <br>
* <pre>{@code if (obj instanceof String s) {
* // can use s here
* } else {
* // can't use s here
* }}</pre>
* <br>
* <br>
* <h3>JDK14 Grammar</h3>
* Per JEP305:
* <br>
* <pre>{@code RelationalExpression:
* ...
* RelationalExpression instanceof ReferenceType
* RelationalExpression instanceof Pattern
*
* Pattern:
* ReferenceType Identifier}</pre>

* <h1>The instanceof statement</h1>

* <h2>Java 14</h2>
* Since JDK14, it is possible to bind a variable that is cast to the type being tested against.
* This is referred to as a {@code Pattern} within <a href="https://bugs.openjdk.java.net/browse/JDK-8181287">JEP305</a>,

* Example:

* ^^^^^^^

* <br>Note: While this is exclusively used within {@code instanceof} operators for now, JEP305 suggests this might
