+ * Unsolved problem: if a type is actually a pointer type, like
+ * nid_triple is, then its impossible to get a const where you need
+ * it. Consider:
+ *
+ * typedef int nid_triple[3];
+ * const void *a_;
+ * const nid_triple const *a = a_;
+ *
+ * The assignement discards a const because what you really want is:
+ *
+ * const int const * const *a = a_;
+ *
+ * But if you do that, you lose the fact that a is an array of 3 ints,
+ * which breaks comparison functions.
+ *
+ * Thus we end up having to cast, sadly, or unpack the
+ * declarations. Or, as I finally did in this case, delcare nid_triple
+ * to be a struct, which it should have been in the first place.
+ *
+ * Ben, August 2008.
+ *
+ * Also, strictly speaking not all types need be const, but handling
+ * the non-constness means a lot of complication, and in practice
+ * comparison routines do always not touch their arguments.
