Taking bets on when ISO C will acquire a form of templates, or taking it in even more generic direction - parametrized namespaces. Something like this (an illustrative example, don't knock me down for including val into list): namespace(T) { struct list { T val; list * next; list * prev; }; void append(list * l, list * i) { ... } } Then list<int> * foo, * bar; ... append(foo, bar); No need for namespace nesting, default arguments and other ++isms. Just something to replace multi-line macro blocks.
