ScopeStack Variadic Allocator Thingy

/* Basically, taking advantage of VS's variadic macros (http://msdn.microsoft.com/en-us/library/ms177415(v=vs.80).aspx), notice the allocation call inside of the macro: */
#define stack_new(type, sa, ...) new (sa.Allocate(sizeof(type))) type(__VA_ARGS__);

/* So all you'd do is pass in the type, allocator, and the class's parameters, and you're good to go without the yucky template specialization: */
{
  StackAllocator stack_alloc(linear_allocator);

  SomeObject* so = stack_new(SomeObject, stack_alloc, param1, param2, param3, param4); //etc.
