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.
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.
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:
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.
You can access argument as only $_ and cannot access as @_, $_[n].
