> If the embedding application doesn't call PySys_SetArgv or PySys_SetArgvEx, then there is no `argv` attribute defined in the sys module (I wasn't actually sure what happened in that case, so I went and checked the code).
Ok, so just don't define sys._raw_argv in that case. But it doesn't seem enough to me to justify to make the attribute private.
https://docs.python.org/dev/library/sys.html#sys.getallocatedblocks can be seen as an implementation detail.The method name has no underscore prefix, but a simple fallback: return 0 if the feature is is not implemented.
