Hello, I'd like to propose a new feature for forms.
Currently if you need a form field with some extra features you can just subclass from django.forms.Field and add all the features you need. However as soon as you're in a template and want to access the field you will get a BoundField instead of your custom field. The need to differentiate BoundField and Field is clear but it would be nice if it was possible to also customize BoundField. For this reason I propose adding a new method "bind_to_form()" to django.forms.Field. It takes a form and a name and returns a BoundField specific to the Field instance. The default implementation just returns an instance of the existing BoundField but now it is possible to customize it. To make it easier, BoundField should become public API. That means it should be able to import it with "from django.forms import BoundField" in order to subclass it. In [1] you can see an implementation of bind_to_form(). I also wrote BoundChoiceField as an example that allows better access to the choices. In [2] you can see how this could be used. Considering BoundField wasn't really public before, this change shouldn't bring any backwards incompatibilities since the default behaviour stays the same. In my test branch all tests pass. I'd really like to hear your feedback on this. If this sounds reasonable I will start writing documentation and possibly drafting a DEP if that's needed.
