From #1179

In Python, it should be possible to refer to enum members: MyEnum.Member, and to create arbitrary enum values from int explicitly like this: MyEnum(42). But by default a number and a value of some enum should not be freely convertible to each other. E.g. this should fail:

void Method(MyEnum value) => ...;

Python:

Method(42); # <- this should be a TypeError

We can add a generic enum codec, that could be enabled on demand to restore old behavior.
