It depends how the NSArrays you deal with are implemented (remember
that NSArray is a class cluster -- in other words, a semi-abstract
class). For instance, in F-Script we make extensive usage of NSArrays
(in particular arrays of NSNumbers), but we do so using an
implementation that transparently make them as small and as fast as C-
style arrays, in most cases.
