well, my final solution is
package Test;
use Moose;
sub new {
my $class = shift;
my $params = $class->BUILDARGS(@_);
my $obj;
if ( $params->{ver} == 1 ) {
require T::V1;
$obj = T::V1->new($params);
} else {
require T::V2;
$obj = T::V2->new($params);
}
return $class->meta->new_object(
__INSTANCE__ => $obj,
@_,
);
}
any comment are welcome. Thanks.
