SYNOPSIS

         use v5.14;
         use Attean;
         my $iter = Attean::CodeIterator->new(
           generator => sub {
             state $value = 0;
             Attean::Literal->new(++$value)
           },
           item_type => 'Attean::API::Term',
         );

         say $iter->next->value; # 1
         say $iter->next->value; # 2
         say $iter->next->value; # 3

DESCRIPTION

       The Attean::CodeIterator class represents a typed iterator.  It conforms to the Attean::API::Iterator
       role.

       The Attean::CodeIterator constructor requires two named arguments:

       generator
           A code reference that when called will return either the iterator's next item, or undef upon reaching
           the end of iteration.

       item_type
           A Type::Tiny object representing the type of the items that will be returned from the iterator.

METHODS

       "next"
           Returns the iterator's next item, or undef upon reaching the end of iteration.
