Didn't see the original, but if those are attributes, why wouldn't
it just be:
for grep { .smoker and .age > 18 } @Subscribers {
.send($ciggie_ad)
}
'Course, this might be more readable:
for @Subscribers {
.send($ciggie_ad) if .smoker and .age > 18;
}
Most smokers don't know what "grep" means, after all...
