I added the examples as tests to S05-modifier/ii.t with commit https://github.com/perl6/roast/commit/3c01d7057c.
The tests pass for MoarVM and JVM. Since support for Parrot was suspended with Rakudo Star Release 2015.02, I'm closing this ticket as 'resolved'. I'll add the ticket to a list of closed ticket living in the mu repository: https://github.com/perl6/mu/blob/master/misc/rt.perl.org/tickets_closed_parrot_only.txt. In case support for Parrot will be restored in some future release the listed tickets can be checked and re-opened as appropriate.
