print Dumper([uniq(@x,@y)]);

print "sorted unique results\n";
print Dumper([sort uniq(@x,@y)]);

输出是

$VAR1 = [
          3,
          2,
          4
        ];
sorted unique results
$VAR1 = [
          2,
          3,
          3,
          4
        ];

因此看起来排序不适用于uniq.我不明白为什么.

我用-MO = Deparse运行perl脚本并得到了

use List::MoreUtils ('uniq');
use Data::Dumper;
use strict 'refs';
my(@x) = (3, 2);
my(@y) = (4, 3);
print "unique results \n";
print Dumper([uniq(@x, @y)]);
print "sorted unique …
