@elijahbenizzy I am very excited for this! What do you think about including freethreaded python in the actions matrix (3.13t)? Maybe we are not ready to go on record as supporting free threading, but it might be nice to keep an eye on it. What do you think?

@elijahbenizzy I am still using AWS Glue Python Shell jobs which are still on Python 3.9. I hope AWS does something soon. I trust the current version of Hamilton will work fine with Python 3.9? I guess I won't get future enhancements and patches until I upgrade.

Looks good to me!

For future work, Python 3.10 allows us to use | in typing.
