Also, if the submit results in a database insert, and the insert fails. I think.
And if there's a formname mismatch.
It seems to me that if accepts() fails, there always ought to be a reason
reported. Would it break compatibility to report these errors in form.errors?
If so, how about creating form.formerrors and guaranteeing that if accepts
returns False, formerrors will say why.

...but that's not really true. There are several reasons for failure that are
not reported in form.errors.
(One of them is that the form has not been submitted yet. I find that logic
really confusing: what's the path, exactly?)
