Description

We stumbled over this code:

    form.is_valid()
    if form.cleaned_data.get('cancel'):
        ...

We did not understand why form.is_valid() is necessary.

It seems that form.cleaned_data is not a property, you need to call is_valid() first.

It would be nice if Form.cleaned_data is be a property, this way the following code would just work:

    if form.cleaned_data.get('cancel'):
        ...

I don't think an implicit call to is_valid() is a good idea. Most of the time, you do want different handling for valid and invalid forms. Of course, you could write your own subclass of Form which has the behavior you desire.

Feel free to raise the idea on the DevelopersMailingList for other opinions.
