=head1 NAME

List::Objects::WithUtils::Role::Array::Typed - Type-checking array behavior

=head1 SYNOPSIS

  # Via List::Objects::WithUtils::Array::Typed ->
  use List::Objects::WithUtils 'array_of';
  use Types::Standard -all;
  use List::Objects::Types -all;

  my $arr_of_arrs = array_of( ArrayObj => [], [] );

=head1 DESCRIPTION

This role makes use of L<Type::Tie> to add type-checking behavior to
L<List::Objects::WithUtils::Role::Array> consumers.

The first argument passed to the constructor should be a L<Type::Tiny> type:

  use Types::Standard -all;
  my $arr = array_of Str() => qw/foo bar baz/;

Elements are checked against the specified type when the object is constructed
or new elements are added.

If the initial type-check fails, a coercion is attempted.

Values that cannot be coerced will throw an exception.

Also see L<Types::Standard>, L<List::Objects::Types>

=head2 type

Returns the L<Type::Tiny> type the object was created with.
