As of 3.13, Python doesnt have a GIL either. JVM-based Ruby implementations don't have a GIL. Perl on the other hand never had a GIL, it just more or less defeated the purpose of threading by copying the entire interpreter state including all variables in every thread. Modules that explicitly work with threading are as rare as hens teeth on CPAN, it's almost always some flavor of async like Coro (hell I bet POE still works too).
python 3.13 most certainly has a GIL, it can just be optionally disabled, and this feature is in experimental status. see https://peps.python.org/pep-0703/
Oh, I thought the experimental state was earlier and that 3.13 was the official no-GIL release. Presumably it's going to eventually drop the GIL entirely (probably Python 4 if there ever is such a thing) but nonetheless I stand corrected, thank you.
