Agreed. The new macros don't really add any type safety, since they rely
on implicit conversions from void*. I'm also *very* scared of the
implicit, hidden qsort in the sorted.

It would make sense to design type-safe, light-weight container and
iterator template wrappers around the APR structures if we decided to
write code in C++. Since we're not, "explicit is better than implicit".
