# List::Util

Native implementation of List::Util

Provides list utility functions (first, sum, min, max, reduce, etc.)

# Perl Equivalent

This module provides Rust-native implementations of functions from List::Util.
Since PetaPerl does not support XS, these are implemented directly in Rust.

# Block-Based Functions

Functions like `first`, `any`, `all`, `none`, `notall`, and `reduce` in Perl
take a block argument. These use the `&@` prototype which tells the parser
to treat `func { block } @list` syntax correctly.

# Synopsis

    use List::Util qw(sum min max first any all reduce uniq);

    my $total = sum @numbers;
    my $smallest = min @numbers;
    my $largest  = max @numbers;

    my $found = first { $_ > 10 } @numbers;
    my $has_neg = any { $_ < 0 } @numbers;
    my $all_pos = all { $_ > 0 } @numbers;

    my $product = reduce { $a * $b } @numbers;
    my @unique  = uniq @strings;
