New description:
Right now only cleaned data is acessed in a dict in python.
This means that type hcecking code does not know the type of that dict
unless it is described as a typeddict.
How about providing type safe access to form field data?
{{{
class FormOptions(forms.Form):
prompt = forms.CharField(widget=forms.Textarea)
n = forms.IntegerField(min_value=1, max_value=10, initial=1)
form_options = FormOptions({'prompt': 'a', 'n': 2})
}}}
one could access it as:
form_options.prompt.cleaned_data
or
form_options.prompt
This would allow code to access type safe values for a form in python.
