No. Python differentiates between functions and methods on a class (particularly, bound methods are separate from functions). The latter require a "self" parameter, which is why there's a difference. You can use an unbound method where a function is expected, but then the caller has to know to pass in the equivalent of "self" as the first argument. There are a number of places in Django that accept a function, but aren't in a position to pass in "self" (and we don't want to do the introspection every time to work out if it's necessary, even if that was always possible, since it's almost always unnecessary overhead). So the real issue here is that the model instance isn't used when computing the choices. That's just the way things are.
