There was a problem hiding this comment.
Yes, but please check that there is no such comparison in marshal.rst as well (maybe we have this kind of mention in marshal.rst, idk)

@picnixz The only 4 mentions of the pickle module in marshal.rst seem to be about RPC calls and where pickle can be used. Nothing that suggests marshal doesn't support recursion or object sharing. So i think this is fine |

Removes an outdated section in the
picklemodule documentation that incorrectly statesmarshaldoes not support object sharing or recursive objects.As confirmed by core developers,
marshal(protocol version 3+) supports both shared references and recursion, making the previous claim inaccurate. This change simply removes the incorrect statement without adding further comparisons, as requested.Fixes #143298
