[Python-ideas] Re: dataclass field argument to allow converting value on init

What type hint will be exposed for the __init__ parameter? Clearly, it's not a `str` type in your example; you're passing it an `int` value in your example. Presumably to overcome this, you'd need yet another `field` function parameter to provide the type hint for the `__init__` param?

Can't this be derived from the type `default_factory` function? `chr` is something like:

def chr(num: int) -> str:

So that type should be `int`.
