Oh, I see.
Wouldn't it be better than to map failed arguments to corresponding
formencode.Invalid exceptions.
For simple error handling and reporting one can than just iterate
through arguments and display an error message where appropriate.
Taking it a step further, such behaviour could be integrated into
widgets themselves, requiring not code what so ever to handle simple forms.

Probably I am overlooking something but for the life of me I can't work

If I understand correctly, it just fills all omitted keyword arguments
with None. But isn't this what the defaults are for?
Not exactly. This is for the current error handling scheme... Let's
say you have something like this:
@turbogears.expose()
@turbogears.validate(form=myform)
def save(self, name, age):
if cherrypy.request.form_errors:
...
If "age" is expected to be an int and comes up invalid, I don't want
to pass the bad value into the method. So, the invalid values just get
turned into Nones and the method being called can decide what to do
with the errors. @error_handler would likely make this cleaner and
probably remove the need for call_with_errors.
