Hm, I am surprised to find that you are right. That does not
make sense. static asserts from Phobos should trigger.
Somewhat off topic, but this makes me wonder, what is the
intended way of resolving these issues? (My guess is that they
are what triggered the discussion anyway.)

Basically, when dealing with containers, a programmer can wish
for two mutually exclusive ways:
1. (normal operation) The containers show the advertised
asymptotic.
2. (paranoia) The containers are checking their integrity after
each operation. This could help e.g. when then comparison
function is flawed in some non-obvious way (is not transitive).
A "-debug=BinaryHeap" seems like a good way to give 2. Perhaps
the same can be done for RedBlackTree? Such checks are not
exactly unit tests, they vary from one application of a container
to another.
