# List::Objects::WithUtils::Hash::Immutable(3pm)

Immutable hash objects

## NAME

List::Objects::WithUtils::Hash::Immutable - Immutable hash objects

## SYNOPSIS

```
  use List::Objects::WithUtils 'immhash';
  my $hash = immhash( foo => 1, bar => 2 );
```

## DESCRIPTION

These are immutable hash objects; attempting to call list-mutating methods (or modify the backing hash directly) will throw an exception.

This class consumes the following roles, which contain most of the relevant documentation:

List::Objects::WithUtils::Role::Hash

List::Objects::WithUtils::Role::Hash::Immutable

(See List::Objects::WithUtils::Hash for a mutable implementation.)

### immhash

Creates a new immutable hash object.
