I am curious. Would it not be possible to implement a class that
handles memory allocations of the standard STL style and just pass an
instance of that allocator (after allocated on the stack of course) to
the stl::vector template parameter, or does std::vector require a
class type? I have not read the standard in this area, and from above
I guess the C++0x is more clear on this?
