# Example alternatives to map, grep, and sort in Perl
# Using List::Util for map-like behavior
use List::Util qw(reduce);
my @numbers = (1, 2, 3, 4, 5);
my @squared = map { $_ * $_ } @numbers; # traditional map
my @alternative = reduce { $a + $_ * $_ } 0, @numbers; # using reduce
# Using List::MoreUtils for grep-like behavior
use List::MoreUtils qw(any);
my @mixed = (1, 2, 3, 'a', 'b', 'c');
my @filtered = grep { !looks_like_number($_) } @mixed; # traditional grep

# Using native sort alternatives

my @sorted = sort { $a <=> $b } @unsorted; # traditional sort
my @reverse_sorted = reverse sort { $a <=> $b } @unsorted; # reverse sorting
