in reply to Benchmark, -s versus schwartzian

On my Windows XP Perl 5.8 system the Schwartzian runs about 5 times as fast as the sort (with the glob inside the loop).

Benchmark: running Ordinary, Schwartzian for at least 2 CPU seconds...
  Ordinary:  2 wallclock secs ( 0.42 usr +  1.75 sys =  2.17 CPU) @  5
+.06/s (n=11)
Schwartzian:  2 wallclock secs ( 0.68 usr +  1.45 sys =  2.13 CPU) @ 2
+3.91/s (n=51)
