Owned boxes shouldn't be commonly used. There's close to no reason to use one for anything but a recursive data structure or in rare cases for an owned trait object. http://static.rust-lang.org/doc/master/tutorial.html#boxes It's important to note that ~[T] and ~str are not owned boxes. They're just sugar for dynamic arrays, and are common containers.
