    Research direction

    Start with the linked BPO issue 37297 and the historical 0001-fix-bound-method-reduce-bug.patch file. Reproduce the reported change in function behavior when pickling a bound method, then compare the result with the patch and identify the relevant library tests. Done means the reported behavior is corrected and covered by regression testing.
