The inablility for Vector to desctruct T[n] is a consequence of inherited inability for a function to return a c array.

For example

     T Vector::pop();

requires the housed type T be returnable.

There is no reason for c++ to systematically disallow it other than c says so, and there is liitle or no incentive for c++ to do otherwise, as it can be easily circled around.

We can have our Vector to work with T[n] if it's really really desirable, by encapuslating it in an intermediate struct Vector::ArrayWrapper automatically.
ArrayWrapper is contructible from, assignable from, convertible to the array type.

There is some work involved. And the requirement is less common to make it worthy.
