List::Objects::WithUtils::Array::Immutable - Immutable array objects

  use List::Objects::WithUtils 'immarray';
  my $array = immarray(qw/ a b c /);
  my ($head, $rest) = $array->head;

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

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

List::Objects::WithUtils::Role::Array

List::Objects::WithUtils::Role::Array::WithJunctions

List::Objects::WithUtils::Role::Array::Immutable

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

Creates a new immutable array object.
