unique_ptr actually doesn't need extra work from the user - if you use
unique_ptr<T[]> instead of unique_ptr<T>, that is.

shared_ptr isn't ideal for holding arrays (doesn't provide operator[]
for one thing) but, yes, with a custom deleter it can at least do so
correctly

(& of course with custom deleters both of these can handle completely
unrelated resource allocation/deallocation strategies)
