I think the method you're suggesting uses global variables, doesn't it
No. I'm thinking about templating the allocator with a make_-style function
that reutnrs an object of type T and then copying its value into the object
that you're allocating. So somewhere in the allocator you'd have:
This also won't result in the copy that it might seem to require. Most
(all?) compilers will optimize it out.
