liblist-moreutils-xs-perl 0.430-3build3 (s390x binary) in ubuntu noble

 List::MoreUtils::XS is a backend for List::MoreUtils. Even if it's possible
 to have it practically independent from List::MoreUtils, it technically
 depends on List::MoreUtils. Since it's only a backend, the API is not public
 and can change without any warning.
 .
 List::MoreUtils provides some trivial but commonly needed functionality on
 lists which is not going to go into List::Util.
