True, but don't forget that using arrays does not imply imperative programming 
in general. For example, I partook in a thread on c.l.functional recently, 
comparing the performance of the sieve of Erasthenes (I know, a 
microbenchmark) in different languages. With a purely functional 
implementation of arrays, the Haskell implementation beat C++ (with 
vector<bool>) and was even competing with OCaml for a short while!
