I didn't state my point well. What you appear to be suggesting is a special case of what given does: topicalize something so you can both test and reuse it. I understand the usefulness of defined-or, and I understand the usefulness of given, but I don't see the need for something in-between.

I say this notwithstanding that some time ago I mused on a similar (not identical) notion. It didn't generate much excitement, either.

I haven't gotten much into Perl6, myself, so I can't even translate your example into a given construct, not that it would be excitingly terse if I did. Can you write a function that would do what you want?
