New submission from Eric V. Smith <[email protected]>:
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
