My internet connection to YAML bug report is bad, so I firstly post my question here. 
#!/usr/bin/perl
use strict;

use YAML qw/Dump Bless/;
use YAML::Node;

{

    package Foo;
    use Moose;
    has foo => (
        is  => 'rw',
        isa => 'Any'
    );
    has bar => (
        is  => 'rw',
        isa => 'Any'
    );
}

my $foo = Foo->new(
    foo => 'fooValue',
    bar => 'barValue'
);
Bless($foo)->keys(['foo']);
print "##### Moose obj #####\n";
print Dump $foo;

my $bar = {
    foo => 'fooValue',
    bar => 'barValue'
};
Bless($bar)->keys(['foo']);
print "##### hashref #####\n";
print Dump $bar;

It seems that the "keys" system do not affect Moose object at all...
