in thread Advanced Sorting - GRT - Guttman Rosler Transform

Be careful which Perl version you are using. I ran the (corrected) benchmark under perl v5.6.1 and got this:
Rate st grt bare bare 4.55/s -- -51% -66% st 9.32/s 105% -- -31% grt 13.5/s 196% 44% --
But under perl v5.8.0 I got this:
Rate st grt bare st 9.43/s -- -15% -37% grt 11.1/s 18% -- -26% bare 15.0/s 59% 35% --
which seems to negate the use of GRT or ST sorting.
