       List::UtilsBy::XS is XS implementation of List::UtilsBy.  Functions are more fast than original ones.

       Same as List::UtilsBy

       List::UtilsBy::XS implements following functions.

       sort_by
       nsort_by
       rev_sort_by
       rev_nsort_by
       max_by (alias nmax_by)
       min_by (alias nmin_by)
       uniq_by
       partition_by
       count_by
       zip_by
       unzip_by
       extract_by
       weighted_shuffle_by
       bundle_by

       This library is free software; you can redistribute it and/or modify it under  the  same  terms  as  Perl
       itself.

       Some  functions  are  implemented  by  lightweight  callback  API.  "sort_by", "rev_sort_by", "nsort_by",
       "rev_nsort_by",  "min_by",  "max_by",  "nmin_by",   "nmax_by",   "uniq_by",   "partion_by",   "count_by",
       "extract_by", "weighted_shuffle_by" are limited some features.

       Limitations are:

   Don'tchangeargument$_incodeblock
       List::UtilsBy  localizes  $_  in the code block, but List::UtilsBy::XS doesn't localize it and it is only
       alias same as "map", "grep". So you should not modify $_ in callback subroutine.

   Can'taccesstoargumentsas@_incodeblock
       You can access argument as only $_ and cannot access as @_, $_[n].

         use List::UtilsBy::XS qw(sort_by);

         sort_by { $_->{foo} } @hash_ref_list

       You can use those functions same as List::UtilsBy ones, but some functions have limitation. See
       LIMITATION section.
