I agree that List::Util::uniq would be nicer but it only made the transition to the core module in 5.26 which I don't have installed on this box (and I haven't installed List::MoreUtils yet after having to rebuild after Meltdown & Spectre patches killed it). You are right about the first line not being discarded, missed that entirely :-/

Cheers,
