Broken in what way? It has a fairly extensive test suite in https://github.com/python/cpython/blob/master/Lib/test/test_index.py (and some additional indirect testing in test_slice.py, which assumes that it works as advertised). > That doesn't change my other point that some > functions that could previously take non-int arguments can no > longer--if we agree on that at least then I can set about making a bug > report and fixing it. The size_t, ssize_t and void pointer conversions should only accept true integers (so either no fallback, or fall back to `__index__`). The unsigned long and unsigned long long conversions should likely be consistent with their signed counterparts and allow lossy conversions via `__int__`. I'm less sure about the conversion to double, but allowing that to be used on float objects without reporting a type error seems like a bug magnet to me.
