I wouldn't say it's better. It would be just a bit more suitable in a 
situation where you know that you will deal with a fixed number of elements 
at runtime. The interface would be probably similar to std::vector but 
without inserting/removing operations. While std::vector is the natural 
choice when you need a dynamic array and boost::array when you know the 
(fixed) size at compile time this new array type (whatever the name would 
be) would be chosen when you know the (fixed) size only at runtime.
