Here's some benchmark code which shows there's not much difference at all using bind values.

I suspect tye's explanation above is correct.

> ./test.pl
Benchmark: timing 50000 iterations of bind, inline...
      bind: 53 wallclock secs (23.00 usr +  8.93 sys = 31.93 CPU)
    inline: 52 wallclock secs (21.68 usr +  8.98 sys = 30.66 CPU)
