+Subject: [PATCH] Reenable dim for python 3.12
+
+In 3.12:
+
+_PyArg_Parser added an element to the start of the structure.
+So existing positional initialization is off.  Switch to element
+initialization.
+
+_Py_CODEUNIT changed to from an int to a union, but relevant_op
+is passed an int for the return of decoder.opcode, so the parameter
+type is wrong, switch it to int.
+
+The opcode PRECALL was removed, so reduce its handling to 3.11
