Make the typing information optional.
From Raymond Hettinger:
The make_dataclass() factory function in the dataclasses module currently requires type declarations. It would be nice if the type declarations were optional.
With typing (currently works):
Point = NamedTuple('Point', [('x', float), ('y', float), ('z', float)])
Point = make_dataclass('Point', [('x', float), ('y', float), ('z', float)])
Without typing (only the first currently works):
Point = namedtuple('Point', ['x', 'y', 'z']) # underlying store is a tuple
Point = make_dataclass('Point', ['x', 'y', 'z']) # underlying store is an instance dict

I'm going to use "typing.Any" (as a string) if the type information is omitted in the call to make_dataclass(). That way I don't need to import typing. |
