标题: "Can't call method xxxx on unblessed reference at"
当使用了一个非对象的引用来使用方法时，会提示 "Can't call method xxxx on unblessed reference at" 的错误，比如：
[code=perl]#!/usr/bin/perl

use strict;
use warnings;

my $ref = {
a => "hello",
b => "world",
};

$ref->print;
[/mw_shl_code]
运行输出：

$ ./temp.pl
Can't call method "print" on unblessed reference at ./temp.pl line 11.
