std.experimental.allocator and GC.addRange

[Benjamin Thaut via Digitalmars-d-learn]

Lets assume I have a allocator which cains together multiple 
building blocks from std.experimental.allocator and at the end 
there is a mallocator providing the underlying memory. Now I 
alloacte a type which contains a pointer into GC memory. 
Obviously the memory of the mallocator is not scanned by the GC 
so the pointer might become dangling if the GC chooses to 
collect. I'm wondering if std.experimental.allocator has any 
building blocks or mechanism to automatically call GC.addRange.

Kind Regards
