+Subject: [PATCH] Stop accessing None as a dictionary
+
+PyMapping_HasKeyString does not work on None
+Accidentally, it used to return false result on silent errors.
+
+Since Python 3.13, this is what happens instead:
+
+    >>> import pylibmc
+    >>> m = pylibmc.Client(["10.0.0.1"], binary=True)
+    Exception ignored in PyMapping_HasKeyString(); consider using PyMapping_HasKeyStringWithError(), PyMapping_GetOptionalItemString() or PyMapping_GetItemString():
+    Traceback (most recent call last):
+      File "/usr/lib64/python3.13/site-packages/pylibmc/client.py", line 142, in __init__
+        super().__init__(servers=translate_server_specs(servers),
+    TypeError: 'NoneType' object is not subscriptable
+    ...
+    Exception ignored in PyMapping_HasKeyString(); consider using PyMapping_HasKeyStringWithError(), PyMapping_GetOptionalItemString() or PyMapping_GetItemString():
+    Traceback (most recent call last):
+      File "/usr/lib64/python3.13/site-packages/pylibmc/client.py", line 142, in __init__
+        super().__init__(servers=translate_server_specs(servers),
+    TypeError: 'NoneType' object is not subscriptable
+
+When this is run via pytest, it leads to:
+
+    pytest.PytestUnraisableExceptionWarning: Exception ignored in PyMapping_HasKeyString(); consider using PyMapping_HasKeyStringWithError(), PyMapping_GetOptionalItemString() or PyMapping_GetItemString(): None
