I want to read configuration from a file named '1.spec',and then try to print something. Here's my code: 
#!/usr/bin/perl
# test.pl

use strict;
use warnings;

my %cfg;

unless(do '1.spec'){
    warn "can not parse :$@";
    warn "can not do: $!";
    warn "could not run";
}

my @keys = keys %cfg;
my @values = values %cfg;

while(@keys){
    print pop(@keys),'=',pop(@values),"\n";
}

Below is '1.spec', only two lines. 
$cfg{name} = 'philip';
$cfg{age} = '21';

I can not get any print when run 'test.pl'. I read perldoc who says 'Do: Uses the value of EXPR as a filename and executes the contents of the file as a Perl script'. If I write 'print "hello"' in 1.spec, it can print as expected, but why it can not set the hash values?
