yes, if we can manage it not to break CI

Thank you for detailed explanation. The metaclass issue is recently solved. Here is the test: ```sh $ cat t.py class _CDataMeta(type): def __mul__(self, length): return create_array_type(self, length) class SimpleType(_CDataMeta): pass...

by watching `rustpython_vm::builtins::pytype::new`, I feel like that'd be simply done by replacing `typ` field in `PyObject`, but not sure it actually will be that easy. Because I don't understand this...

What happens when the buffer is destroyed? Does it deletes only the pointer(as a reference) or also deletes the data it contains (as an owner)? If it does both, then...

If it doesn't fit in rust lifetime, creating a similar enum will fit. ```rust pub enum RawBuffer { Borrowed(*mut [u8]), Owned(Box), } ```

I never used it myself before, but `Add suggetion to batch` button exist.  But I don't think it will work well. I suggested one side of code but didn't...

@darleybarreto this must be what you are looking for, right? ```python >>>>> import ctypes >>>>> ctypes._SimpleCData >>>>> type(ctypes._SimpleCData) >>>>> ```

I just made a test code in commit https://github.com/RustPython/RustPython/pull/2364/commits/efabe9b1b460ff8e2055419a6f5c51856f7c42b7 You can adapt it to any type you actually need to. And sorry for another accidental push-force. that's not what I...

I pushed to your branch. So if you named your repository as `origin`, like when result of `git remote -v` is `origin https://github.com/rodrigocam/RustPython.git`, `git fetch origin && git reset --hard...
