How does this compare with gevent?

Is Python about to have its Project Loom moment?

Why not just use Go?

This is an intimidating amount of code! 12,303 lines of C and 244,740 lines of Python, which looks to be a ton of monkeypatching plus huge amounts of test code. Only one commit added all of that, just two hours ago. The published numbers are impressive, but its hard to evaluate how much trust can be put in a project of this complexity at this early stage.

This is a seriously impressive project. I see your pitch is M:N work-stealing across real cores on free-threaded 3.13t/3.14t which i think is only possible because nogil now exists. which makes gevent seem lackluster in comparison

Why not just use Go, haha?

Does your code have a significant dependency on the version of Python? How easy will it be for you to maintain your code to support Python 3.15, 3.16, etc.? Is it too dependent on the implementation of Python 3.13 and 3.14 or its low level aspects? What is all the Python code doing?
