Already done.  The standard requires that all allocators to be used with 
std::containers (both user supplied and vendor supplied) have the 
interface described in 20.1.5.

So if a client ignorant of the "auto_ptr" in vector writes:

template <class T>
class MyAllocator {...}

vector<MyClass, MyAllocator<MyClass> > v(...);

Then his MyAllocator will get installed into the vector's "auto_ptr" and 
be guaranteed to work because we are all following the standard specified 
interface for allocators.  (assuming we can actually pull all this off!)
