The performance issue of returning a result of an expression without first storing to a variable should be unimportant here. On the other hand that could be better named to eg llIsFamily.

I didn't say it might return an empty or no array. I don't know a case where it does. Even with activex you get a return value > 0 (but not something very usefull for this).

As you said it's personal taste. To me edited version is 'readable at a glance and self exlanatory'. You find llIsFamily better and that's kind of redundancy for me:) 'Is' already denotes a boolean check IMHO and lIsFamily or IsFamily looks better if ever need be.
