You want a C<next> method, and you want the <> operator to do the right
thing in its various contexts. I presume there will be a
close-to-builtin role C<iterator> that does just that:
class MyIterator {
does iterator;
has $.count = 0;
sub next () {
$.count++;
}
}
my $iter = MyIterator.new;
say for <$iter>; # 0 1 2 3 4 5 6 ...
