TypeError: Type Dict cannot be instantiated; use dict() instead

[George3d6]

I'm getting this error, is the package not able to work with the new generic python Typing?

@George3d6, please, attach more information:

• Python version

I encountered a similar exception with lists which might be the same underlying bug: https://github.com/lidatong/dataclasses-json/issues/310

Have just encountered this in my code. It's probably these lines in core.py (around line 267) masking an issue with something inside your dict: try: res = _get_type_cons(type_)(xs) except (TypeError, AttributeError): res = type_(xs) As a work-around I replaced them with these: try: tp = _get_type_cons(type_) except (TypeError, AttributeError): tp = type_ res = tp(xs) which exposed the issue in my dataclass inside my dict.
