87 * Unsolved problem: if a type is actually a pointer type, like
88 * nid_triple is, then its impossible to get a const where you need
89 * it. Consider:
90 *
91 * typedef int nid_triple[3];
92 * const void *a_;
93 * const nid_triple const *a = a_;
94 *
95 * The assignment discards a const because what you really want is:
96 *
97 * const int const * const *a = a_;
98 *
99 * But if you do that, you lose the fact that a is an array of 3 ints,
100 * which breaks comparison functions.
101 *
102 * Thus we end up having to cast, sadly, or unpack the
103 * declarations. Or, as I finally did in this case, declare nid_triple
104 * to be a struct, which it should have been in the first place.
105 *
106 * Ben, August 2008.
107 *
108 * Also, strictly speaking not all types need be const, but handling
109 * the non-constness means a lot of complication, and in practice
110 * comparison routines do always not touch their arguments.
