 ``\z`` is same as ``\\z`` because there's no escape sequence for ``z``. But it is not clear
 for the reader of the code.
+
+The only reason this is demonstrated to raise ``syntax-error`` is because
+pylint's CI now runs on Python 3.12, where this truly raises a ``SyntaxError``.
+We hope to address this discrepancy in the documentation in the future.
