I have a cross-version Python bytecode disassembler xdis (https://pypi.org/project/xdis/) and I notice that flags 0x0100 and 0x0200 (DONT_IMPLY_DEDENT and SOURCE_IS_UTF8 respectively) conflict in Pypy 3.6 with Python 3.6's ITERABLE_COROUTINE and ASYNC_GENERATOR.
Looking in the CPython 3.6 source code, I see that PyCF_DONT_IMPLY_DEDENT = 0x0200 as well there, even though ``inspect.CO_ASYNC_GENERATOR`` is also 0x0200. The same with PyCF_SOURCE_IS_UTF8 = 0x0100 and ``inspect.CO_ITERABLE_COROUTINE``. So the conflict you're talking about seems to exist in CPython 3.6 too. Can you give us a concrete example of code where CPython 3.6 differs from PyPy 3.6? A bientôt, Armin.
