If we expected Perl6 to be able to recognize these series and continue them based on nothing but the first few elements, that would be a dwimmy OEIS. (And an OEIS module that did that by consulting the real OEIS would be cool, outside of core.) But that's not what this is about. This is just wanting to be able to write the ones that have simple mathematical expressions (closed or not) using simple Perl 6 expressions with the series operator.
