 JSON serialization and deserialization module.
 
+This module is not safe. You may not want to use it with untrusted data.
+If you need a safe alternative, consider a 3rd-party library like `cjson`.
+
+You can override the json functions with:
+```c
+py_GlobalRef mod = py_getmodule("json");
+py_bindfunc(mod, "loads", _safe_json_loads);
+py_bindfunc(mod, "dumps", _safe_json_dumps);
+```
