I don't know about the implementation of redblack tree in

if you compare it against an optimized hash table (for example
using robin-hood open addressing techniques). And I guess it is
for sorted set (like a heap) with O(log N) insertion and
deletion (although this may be just a theoretical
worry)...Furthermore, the template constraint indicate the need
of a less predicate which you may not need or want to define.

There, save everyone the trouble of implementing this in the
compiler and complicating the language with special casing by
just using that.
