Thanks for the hints!

If anyone is interested, my result: 
    my $tb = Tree::Builder->new();

    find(sub {
        my $name = $File::Find::name;
        $name =~ s/^$dir//;
        
        $tb->add($name);
    }, $dir);

    my $tree = { $tb->getTree };

    _transformTree( $tree );

        ...

sub _transformTree {
    my $ref = shift;

    ## I need sort of meta-data-enabled tree:
    foreach my $item (keys %$ref){
        if( keys %{ $ref->{ $item } } ){
            my $clone = $ref->{ $item };
            $ref->{ $item } = {};

            $ref->{ $item }->{name} = $item;
            $ref->{ $item }->{value} = $clone;

            # $clone = undef; # should I uncomment this? or does perl 
+take care of it?

            _transformTree( $ref->{ $item }->{value} );
        }else{
            $ref->{ $item }->{name} = $item;
            $ref->{ $item }->{value} = undef;
        }
    }
}
