# Data::Dumper

Native implementation of Data::Dumper

Provides data structure serialization to Perl syntax.

# Perl Equivalent

Data::Dumper

# Synopsis

    use Data::Dumper;

    print Dumper(\%hash, \@array);

    my $d = Data::Dumper->new([$ref], ['name']);
    $d->Indent(1);
    $d->Sortkeys(1);
    print $d->Dump();

# Functions

## Dumper

Dumps one or more references to Perl syntax. Returns a string
containing the serialized representation.

```perl
use Data::Dumper;
print Dumper($hashref, $arrayref);
# $VAR1 = { 'key' => 'value' };
# $VAR2 = [ 1, 2, 3 ];
```

## new

Creates a Data::Dumper object for fine-grained control over
serialization options.

```perl
my $d = Data::Dumper->new([$ref1, $ref2], [qw(name1 name2)]);
print $d->Dump();
```

## Dump

Returns the serialized string from a Data::Dumper object.
Alias: `Dumpxs()`.

## Reset

Resets the internal seen-address cache so the next `Dump()` call
starts fresh (no back-references to previous dumps).

## Indent

Gets or sets the indentation level (0=none, 1=fixed, 2=adaptive).

## Sortkeys

Gets or sets whether hash keys are sorted alphabetically in output.

# Output Format

The output follows Perl's Data::Dumper format:
- Scalar references: `$VAR1 = \'value';`
- Array references: `$VAR1 = [ ... ];`
- Hash references: `$VAR1 = { 'key' => value, ... };`
- Circular references: `\$VAR1->{'key'}` (back-reference to already-seen value)
