I'd hope that such things were lazy in Perl6.

As eric256 pointed out in Re^2: cross combinations, gather and take are indeed lazy in Perl 6. Some folks are angling to get that redacted as the default, but they also recognize how useful it will be in many cases, so their proposals include a simple, convenient way to turn laziness back on. In either event, I think the answer will be Yes. :-)
