Is anyone familiar with Instagram's cinder?
https://github.com/facebookincubator/cinder
cinder includes changes for immutable module objects. I wonder if the implementation is similar? Or is cinder so old that it would be incompatible with the future noGil direction?
I work on cinder, it is primarily a JIT compiler, and does not have this sort of concurrency construct (which looks extremely exciting and well thought out, props to the verona team!).
cinder is actively developed (we recently upgraded it to 3.12) and is definitely going to be compatible with free threaded (nogil) python.
