Proposal:

FunctionsPyDict_GetItem(),PyDict_GetItemString(),PyMapping_HasKey(),PyMapping_HasKeyString(),PyObject_HasAttr(),PyObject_HasAttrString() andPySys_GetObject() have a flaw -- they clear any error raised inside the function, including important and critical errors. They cannot be fixed, because the user code which use them do not handle errors. There are replacements free from this flaw forPyDict_GetItem() (PyDict_GetItemWithError() andPyDict_GetItemRef()) and, in some applications, toPyDict_GetItemString() (PyDict_GetItemRefString()).

We need new functions similar toPyMapping_HasKey(),PyMapping_HasKeyString(),PyObject_HasAttr(),PyObject_HasAttrString() which return three-state value (1 - yes,0 -- no, and-1 --error). What should be their names? Add theWithError suffix? Add theEx sufix? Add the2 suffix?
