b7df2f1c0 "Fix signal initializer.", 18. May 2010 at 00:55 There was a `PySequence_Check` in the evaluation of some signature function parameter processing, which should have been `PyTuple_Check`. Since the new PyEnums are also sequences, the new optimization in Python 3.11 changed the parameter handling in a correct way and replaced the argument tuple by a direct single argument of an enum type. And that is also a sequence ... There are probably still dormant issues like this in the codebase which gives reason to submit a task that checks all Python interface functions for correctness.
