        Suppose we have $_="haha:lala:rere";
        What is faster??
        ($haha) = split /:/, $_;  # or
        ($haha) = split(/:/, $_, 1);

Lots of people weighed in on this matter
Some advised the use of Benchmark
Few noticed that the two samples do not do the same thing
- Or that the second sample is entirely worthless

        # $_ = "a:b:c:d"
        split /:/, $_, 3;              # ("a", "b", "c:d")
        split /:/, $_, 2;              # ("a", "b:c:d")
        split /:/, $_, 1;              # ("a:b:c:d")

        ($haha) = split /:/, $_;       # ("a", "b:c:d")
