Vladimir Filipović added the comment: Hi Raymond! Thanks for the attention you've given this and for the words of encouragement. I'll try to make something like this for PyPI. I do feel I should critique your metaphor of Queues as email. (Please don't take this as a request to re-evaluate

[issue35194] A typo in a constant in cp932 codec

Alexey Izbyshev added the comment: I've added 'assert' to macros. Since 'typeof' seems to be disallowed in Python, I've used 'unsigned int' as the type of an intermediate variable. Another alternative is 'assert(0 <= (c) && (c) <= 255)', but 'c' will be evaluated several times. --

Serhiy Storchaka added the comment: Converting to unsigned int can unnecessary widen the value or truncate higher bits. On other side, testing "0 <= (c)" can emit a compiler warning if c is unsigned. Maybe test "Py_CHARMASK(c) == (c)"? -- ___

[issue35197] graminit.h defines very generic names like 'stmt' or 'test'

STINNER Victor added the comment: > I think it would be better to exclude graminit.h from the set of distributed > headers. It is internal generated file, it should not be used by any user > code. I'm fine with moving it to Include/internal/. Do you know if it's used outside CPython?

[issue35199] Convert PyTuple_GET_ITEM() macro to a function call with additional checks in debug mode

STINNER Victor added the comment: Copy of my comment: https://github.com/python/cpython/pull/10435#issuecomment-437405620 This change breaks the backward compatibility when a C extension is compiled with Py_DEBUG. So I'm not sure that it should be merged into Python 3.8. Maybe we should add
