Comment:
It can be done in a clean way.
You can do it by small rewrite of ErrorList (form Error classes in
general). It have to accept additional param on __init__, the params from
ValidationError or even whole Exception (for custom exceptions handling).
Then you can change the form behaviour by passing custom error_class param
to your Form, and handle this additional param in your custom ErrorList.
But it's not backward compatible for old custom classes. It could be if
you would create new base class for ErrorList and check it by instanceof,
keeping old behaviour too.
