    The proposed PR adds decryption of the MAKE_FUNCTION argument (it is a bits set) in the disassembler output. For example:

    $ echo 'def f(x, y=1, *, z=2): ...' | ./python -m dis
      1           0 LOAD_CONST               6 ((1,))
                  2 LOAD_CONST               1 (2)
                  4 LOAD_CONST               2 (('z',))
                  6 BUILD_CONST_KEY_MAP      1
                  8 LOAD_CONST               3 (<code object f at 0x7fe5ade8f300, file "<stdin>", line 1>)
                 10 LOAD_CONST               4 ('f')
                 12 MAKE_FUNCTION            3 (defaults, kwdefaults)
                 14 STORE_NAME               0 (f)
                 16 LOAD_CONST               5 (None)
                 18 RETURN_VALUE

    Disassembly of <code object f at 0x7fe5ade8f300, file "<stdin>", line 1>:
    1 0 LOAD_CONST 0 (None)
    2 RETURN_VALUE
