New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

C API functions like PyDict_GetItem() and PyObject_HasAttr() suppresses all errors that may occur, including MemoryError and KeyboardInterrupt. They can return incorrect result when the memory is exhausted or the user presses Ctrl-C. The proposed PR documents such functions and suggests the C API which do not swallow unrelated exceptions.

Previous attempt to document this (for PyDict_GetItem() only) was in issue20615.
