New submission from Arnaud Delobelle <arno...@googlemail.com>: The description of the opcode MAKE_FUNCTION in the dis module document is out of date. It still describes the 2.X version of the opcode:
""" MAKE_FUNCTION(argc) Pushes a new function object on the stack. TOS is the code associated with the function. The function object is defined to have argc default parameters, which are found below TOS. """ According to http://hg.python.org/cpython/file/default/Python/ceval.c#l2684: 2684 int posdefaults = oparg & 0xff; 2685 int kwdefaults = (oparg>>8) & 0xff; 2686 int num_annotations = (oparg >> 16) & 0x7fff; So the documentation should read something like """ MAKE_FUNCTION(argc) Pushes a new function object on the stack. TOS is the code associated with the function. The function object is defined to have argc & 0xFF positional default parameters, (argc >> 8) & 0xFF keyword only default parameters, and (argc >> 16) & 0x7FFF parameter annotations which are push below TOS in this order. For each keyword only default, the name of the parameter is pushed just below its default value. On top of all the annotations, a tuple is pushed listing the parameter names for these annotations.
