I took
larsen's advice but did the following. I still cannot get the count to reset before the second sort. Why doesn't calling xcmp the second time reset count?
use strict;
$|=1;
my @list = qw/ box cow dog apple ant/;
sub xcmp{
my $count = 0;
sub get_count { return $count } # an inspector as a closure
# and another closure
sub compare
{
$count++;
return $_[0] cmp $_[1];
}
return(\&compare, \&get_count);
}
my @funcs = xcmp();
print sort { $funcs[0]( $a, $b ) } @list;
print "\n";
print $funcs[1](), "\n";
@funcs = xcmp();
print sort { $funcs[0]( $a, $b ) } @list;
print "\n";
print $funcs[1](), "\n";
