Huh?  Where does it say that a mallocator is required?

As far as I can tell, you could simply do this:

	void[] myBuffer = ...;
	auto allocator = Region!()(myBuffer);
	auto p = allocator.allocate(...);

The default parent allocator is NullAllocator, which does nothing, so
that leaves the management of myBuffer entirely up to you.
