Subject: [PATCH] Initialize PyTypeObjects with PyVarObject_HEAD_INIT
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This fixes the following errors on clang (`Apple clang version 15.0.0
(clang-1500.3.9.4)`):

```
src/infinity.c:271:2: error: incompatible pointer to integer conversion initializing 'Py_ssize_t' (aka 'long') with an expression of type 'void *' [-Wint-conversion]
        PyObject_HEAD_INIT(NULL)
        ^~~~~~~~~~~~~~~~~~~~~~~~
/opt/local/Library/Frameworks/Python.framework/Versions/3.12/include/python3.12/object.h:142:9: note: expanded from macro 'PyObject_HEAD_INIT'
        (type)                   \
        ^~~~~~
```

and the following warnings on gcc (`gcc (Debian 12.2.0-14) 12.2.0`):

```
