( #3333=superdoc: print w/ replies, xml ) Need Help??

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, };

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};

Changing it to:

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

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?
