[dancer-users] Form validation framework

Hello all, is there a generally recommended form validation framework for Dancer? There are several plugins on CPAN, but they all seem to be rather basic (at least on first glance). A key feature for me is that error messages can be easily displayed together with the respective input fields and not only as a group of error messages. Which plugin do you use or do you use your own form validation code? Thanks for your help, Lutz
