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