There's no room for advanced stuff or edge cases.\r\nTesting Limited API together with other C API is complicated, because:\r\n\r\n- Limited API needs to be enabled per source file\r\n- Some builds don't support Limited API, so Limited API tests must be skipped on those builds.\r\n  (Currently this is `Py_TRACE_REFS`, but that may change.)\r\n- `Py_LIMITED_API` must be defined before `\u003cPython.h\u003e` is included.\r\n\r\nWith #95505 (splitting `_testcapi` module into several source files), the first complication is solved. I'd like to add helpers for the others, to make testing Limited API easy.\r\n","author":{"url":"https://github.com/encukou","@type":"Person","name":"encukou"},"datePublished":"2022-08-15T09:17:30.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/95991/cpython/issues/95991"}
