The thing that really struck me after years of python is how it lets you out dependencies directly in a comment on top of a script and it will download and run with them automatically, without poisoning any system settings. It's so simple!
> Does that stay true once the GIL turns back on?
In the current nogil implementation, AFAICS, it seems the GIL can't be turned back on so there is no answer yet.
Theoretically, you could have a one-off operation which fixes all objects when the GIL is turned on. However, there's no way to get all objects in Python. gc.get_objects() only returns tracked objects, and there is no way to list untracked objects.
It seems, three fields are exposed on every CPython object in the stable ABI, any change which affects their offsets will break the stable ABI. https://github.com/capi-workgroup/problems/issues/4#issuecom...
> I'm not following why this affects ABI compatibility, sorry.
True, PyType_FromSpec can set tp_alloc to a wrapper function which papers over the difference in what the "allocfunc" should initialise the memory to.
Re performance - merging the change is the only way people will actually start targeting nogil.
The old-style nix-shell command in Nix can do this[1] for every language and package Nixpkgs supports, although it’s not that often used because it ties your shebangs to Nix. (An equivalent feature for the new CLI is a work in progress[2].)

I believe you just pass objects instead, like you would in OOP, and take the hit of pickling and unpickling them every time.
If you really want to pass lambdas, you can use a third party library to pickle them

Yes, this is not great.
> I'm going to miss the thread-safety non-GIL python offered.
The old method — which is the GIL, or non-non-GIL — provides no thread safety to Python code. It only protects C code
> Can we get an in-python fork() mechanic ... please?
You probably want Multiple Subinterpreters: https://github.com/python/cpython/issues/84692
It's basically becoming reality already, PEP 684 per-interpreter gil is the required structure for this (coming in Python 3.12), now only interface on top of that remains, see WIP like https://github.com/jsbueno/extrainterpreters the full interface to gil-free interpreter threads is coming in
Many that praise async/await in C#, kind of forget it took about 10 years to spread across all the layer of the language and runtime, since it was done via IL rewriting, it caused several issues with F# async tasks, due to the age of the ecosystem plenty of code isn't async/await friendly and needs to be wrapped into Task.Run() or similar.
There is a best practices guideline from one of the ASP.NET architects, https://github.com/davidfowl/AspNetCoreDiagnosticScenarios/b...
During last year they researched adding Go/Java's approach to .NET, but now it is too late. See the ASP.NET Q&A session at BUILD 2023.
