Stackless Python
Shares rank 8 of 9 Python interpreters by recommenders
People recommend it for tasklets that can be serialized and moved to another machine, making it a good fit for long-running stateful work. Its main drawback is that it has not kept pace with mainstream Python, and some developers have moved away from it.
