Are there other options??

plain old:

@dataclass
class C:
    a = 1
    b = 1.0

would work, though then there would be no way to express fields without
defaults:


The PEP already supports using "a = field(); b = field()" (etc) to declare
untyped fields without a default value.

This annotation free spelling may not be clearly covered in the current
module docs, though.

Cheers,
Nick.
