Using my() changes XML::Bare behavior drastically
===

When I run this Perl script: 
 

    #!/bin/perl 
    use XML::Bare; 
    $ob = new XML::Bare(text=>'<xml><name>Bob</name></xml>'); 
    for $i (keys %{$ob->{xml}}) {print "KEY: $i\n";} 

I get no output. However, if I put $ob inside a my(): 
 

    #!/bin/perl 
    use XML::Bare; 
    my($ob) = new XML::Bare(text=>'<xml><name>Bob</name></xml>'); 
    for $i (keys %{$ob->{xml}}) {print "KEY: $i\n";} 

I get this output: 
 

    KEY: _z 
    KEY: _i 
    KEY: xml 
    KEY: _pos 

Why does my() change this behavior so drastically, especially given 
that I'm at the top level where my() should have no effect at all(?).
