I've actually just created a new Callback constraint called
CallbackWithForm that will actually handle it, the changes basically
involve not passing positional arguments but passing a hash of options:
e.g. obj->callback(value => $value, params => $params, form => $self->form)
I've not yet had the chance to really dig into FormFu guts but if
there's a way that $params can be an object with a few methods to
provide $form/$self (while still being accessible as a hashref for
backward compatibility), that seems to be the "nicer" solution in a way.
