+/* A higher-order macro for enumerating all JSProtoKey values. */
+/*
+ * Consumers define macros as follows:
+ * MACRO(name, clasp)
+ *   name:    The canonical name of the class.
+ *   clasp:   The JSClass for this object, or "dummy" if it doesn't exist.
+ *
+ *
+ * Consumers wishing to iterate over all the JSProtoKey values, can use
+ * JS_FOR_EACH_PROTOTYPE. However, there are certain values that don't
+ * correspond to real constructors, like Null or constructors that are disabled
+ * via preprocessor directives. We still need to include these in the JSProtoKey
+ * list in order to maintain binary XDR compatibility, but we need to provide a
+ * tool to handle them differently. JS_FOR_PROTOTYPES fills this niche.
+ *
+ * Consumers pass two macros to JS_FOR_PROTOTYPES - |REAL| and |IMAGINARY|. The
+ * former is invoked for entries that have real client-exposed constructors, and
+ * the latter is called for the rest. Consumers that don't care about this
+ * distinction can simply pass the same macro to both, which is exactly what
+ * JS_FOR_EACH_PROTOTYPE does.
