/**
 * A node object created for LineIdentifierReference lines which use the T_OPERATOR_REFERENCE
 * operator and have a TokenStreamIdentifier stream for "the right side" of the expression.
 *
 * The reference operator is nasty, since it's no "true" reference / pointer:
 * foo.bar = barValue1
 * baz =< foo
 * baz.bar = barValue2
 * This ends up with "barValue1" for "foo.bar", and "barValue2" for "baz.bar". "barValue1"
 * for "foo.bar" is kept!
 *
 * Note the reference operator *only* works for TS "setup" code, not for "constants", and it
 * is only resolved in these cases. See ContentObjectRenderer->cObjGetSingle() for details.
 *
 * @internal: Internal AST structure.
