type.__prepare__ can receive 0 arguments in CPython:
Python 3.9.4 (default, Apr 5 2021, 01:47:16)
[Clang 11.0.0 (clang-1100.0.33.17)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> type.__prepare__()
{}The same happens with 3.8.
But, RustPython requires to pass 2 args:
Welcome to the magnificent Rust Python 0.1.2 interpreter 😱 🖖
