my @array = qw(flow loop pool Wolf root sort tour);
from search.cpan.org/~ewijaya/Sort-Radix-0... yields:
Undefined subroutine &Sort::Radix::radix_sort called at C:\Temp\t.pl line 7.
This seems to be because the sub radix_sort is placed _after_ the __END__ marker in the module file.
Fixing that yields:
Argument "flow" isn't numeric in subtraction (-) at Sort/Radix.pm line 44.
