Well, unexpected to me...

#!/usr/bin/perl
use strict;
use warnings;
use Data::Dumper 'Dumper';
use CGI;

my $q = CGI->new();

my $var = { first  => $q->param('first'),
            second => $q->param('second'),
          };

print Dumper($var);

What do you expect $var to be? I expected

$VAR1 = {
          'first'  => undef,
          'second' => undef,
        };

[download]

What I got was:

$VAR1 = {
          'first' => 'second'
        };

To me, this is unexpected behavior. This is the line that gives us this:

    return unless defined($name) && $self->{$name};

[download]

Changing it to:

    return undef unless defined($name) && $self->{$name};

[download]

gives me the behavior I expect. But, is there a reason why the line as it stands is more correct than my interpretation? Am I the only person who thinks that the current implementation feels wrong?
