Perl split
split doesn't return empty string items for trailing delimiters - split(/;/, "a;;;") returns just 1 item, "a".
Similarly in the degenerate case where the string consists entirely of delimiters, no items are returned at all.
Leading delimiters, on the other hand, generate empty items as you'd expect. split(/;/, ";;a") returns 3 items - ("", "", "a").
