@ -42,6 +42,8 @@ Use cases:
 * frozendict avoids the need of a read-only proxy in some cases. frozendict is
   faster than a proxy because getting an item in a frozendict is a fast lookup
   whereas a proxy requires a function call.
+ * use a frozendict as the default value of function argument: avoid the
+   problem of mutable default argument.
