I actually have my own prototype implementation (attached) that I used to 
test my ideas of how unique_ptr<T[]> and unique_ptr<T[N]> should behave with 
respect to conversions between them (modeled after shared_ptr.)

It's however a prototype; meaning that it relies on C++11 features, does not 
optimize out empty deleters, has no tests. I used the libc++ test suite to 
test it, but that's not suitable for Boost.

It didn't occur to me that Howard has already written the test suite in a 
more suitable form. :-)

I intended to eventually bring this up to production quality and make it 
boost::unique_ptr, but couldn't spare the time.

That exactly what I did too. :-)
