Works in both python3.6 and python3.7 ```python def is_list_type(tp) -> bool: """ Test if the type is a generic list type, including subclasses excluding non-generic classes. Examples:: is_list_type(int) == False...

Three years have passed. The issue is still not resolved. What a great app!

Actually, it DOES concatenate... If you create the following config, the `+=` would work... but NOT as intended: ```pyhocon x = [1, 2] d { x = [1,2] x +=...

Also, according to https://hocon-playground.herokuapp.com/, the `+=` operator SHOULD NOT extend arrays, only append elements, which, ironically, pyhocon can't do.

Actually, does not fail on the following: ```hocon HOCON = Human-Optimized Config Object Notation Default = [ { Name = Foo} ] dev2= [{ Name = Foo2}] dev3= [{ Name...

The following tests fail for me (Win) on Python 3.7 and Python 2.7 

@gshpychka, you can try the following: 1. Define the DataClassJsonMixin-nested class A 2. Define class B which *is not* dataclass on its own 3. In class B, define the required...

IMAO, this is working as intended – DCJ's method `to_json` serializes data so it can then be deserialized. Otherwise, the following won't work: ```python j = session.to_json() s2 = Session.from_json(j)...

@George3d6, please, attach more information: - Python version - OS - Code fragment invoking the error - Stack trace

Added tests covering that case. Before the fixes they fail on the following: [bug-341-test-reports.zip](https://github.com/lidatong/dataclasses-json/files/8311656/bug-341-test-reports.zip) ### Failed tests summary #### Python 3.6: - `list` - `Set` - `set` - `Tuple` -...
