+Subject: [PATCH] Unicode::UCD::prop_invlist() Allow to return internal
+ property
+
+This creates an optional undocumented parameter to this function to
+allow it to return the inversion list of an internal-only Perl property.
+This will be used by other functions in Perl, but should not be
+documented, as we don't want to encourage the use of internal-only
+properties, which are subject to change or removal without notice.
