Alternatively, yet still using the idea of discarding part of the output:

my(undef, undef, @rest) = split/\n/;
But, with a variable value for $index, I'd rather go the splice route.

    Yeah, I thought of that one, but ultimately didn't use it because, as you mentioned, it doesn't work well with an arbitrary starting index.

    You could do something like this:

    my $str = "discard\ndiscard\nkeep1\nkeep2"; my $index = 2; my @arr = grep {$index-- <= 0} split "\n", $str;
