Any C/C++ extensions that wants to enable more efficient Python has to learn GIL and how to manipulate that as well. Including not limited to: how to give up GIL (so that other Python code can progress); how to prepare your newly initiated threads to be Python GIL friendly etc. Personally, GIL is more surprising to me when interop with Python.

Including not limited to: how to give up GIL (so that other Python code can progress); how to prepare your newly initiated threads to be Python GIL friendly etc. Sure, but the easy cases are easy (in particular, you can usually do nothing and it will be correct but slow, which is much better than fast but incorrect) and the hard cases are possible. > Personally, GIL is more surprising to me when interop with Python. Any GCed language, including Go, will oblige you to integrate with its APIs if you want to handle complex cases correctly.
