I'd rather use a custom validator. The logic is clearer, you write less
repetitive code, you reuse more components, no changes to TG are required,
you can have all that *now*.
Also, your changes imply in changing how TG is working with FormEncode.
What I see is that this would bring more harm than good and would add extra
code that needed to be maintained in TG.
On the other hand, nothing prevents you from coding that: you can create new
decorators and make them do what you want. There are three dicts that you
can use (that I remember right now, maybe there's something more): you can
get your submited data with a **kwargs dictionary, you can check (/set?)
validation errors on tg_errors and you can send back values on a dict of your
own to be redisplayed on the form.
So, even though there's no written code on TG core that does what you want,
you can get it to work like that in, lets say, one weekend.
