EXAMPLES
  A basic range
    This example implements a range generator from $from until $to. In order
    to generate this range we define 2 callbacks: `on_has_next()' and
    `on_next()'. The first one is used as point of truth whether the
    sequence has any more non-iterated elements, and the 2nd one is here to
    return the next element in the sequence and the one that changes the
    state of the internal sequence iterator.

      sub basic_range {
        my ($from, $to) = @_;
        $from <= $to or die '$from should be less or equal $to';
        my $current = $from;
        Data::Enumerable::Lazy->new({

=head2 A basic range

This example implements a range generator from $from until $to. In order to
generate this range we define 2 callbacks: C<on_has_next()> and C<on_next()>.
The first one is used as point of truth whether the sequence has any more
non-iterated elements, and the 2nd one is here to return the next element in
the sequence and the one that changes the state of the internal sequence
iterator.
