in reply to Why should I use perl 5.10?

It's a seamless and logical update from 5.8. Why would there be a need for any marketing besides this ?

    Plus 5.10 is faster, smaller, and cooler. What more do you need? O yeah, how about switch/case statement and named captures in regexp as a couple of bonuses, among many others? Those are features many Perl programmers have been waiting for ages, and finally their wishes have been fulfilled.

    All you need to do is upgrade your OS distribution or install a fresh box in a few months, and Perl 5.10 will most probably be there, ready for use.

    You can just use 5.10 as if it were your old 5.8. Discover new cool features as you go, at your pace. Really, there's NO risk.

      Faster? Anyone got some numbers to prove this?

        use Benchmark; timethese(100000, { 'Test' => 'eval{die "x" x 100000 if $] < 5.01}', });
        Under perl 5.8:
        Benchmark: timing 100000 iterations of Test... Test: 15 wallclock secs (14.98 usr + 0.00 sys = 14.98 CPU) @ 66 +73.34/s (n=100000))
        Under perl 5.10:
        Benchmark: timing 100000 iterations of Test... Test: 0 wallclock secs ( 0.02 usr + 0.00 sys = 0.02 CPU) @ 62 +50000.00/ (n=100000) (warning: too few iterations for a reliable count)
        Whooooo ... how good is *that* !!!!!

        Cheers,
        Rob
