Hello,
I know it's been a long wait. Hopefully it was worth it. The
alpha release of untyped allocators is ready for tire-kicking
and a test drive.
Code:
https://github.com/andralex/phobos/blob/allocator/std/allocator.d
Dox: http://erdani.com/d/phobos-prerelease/std_allocator.html
Warning: this is alpha quality. Unit tests are thin, and there
are no benchmarks. Both would be appreciated, particularly
benchmarks to validate the gains (which I speculate can be very
sizable) of custom-built, special-purpose allocators compared
to traditional allocators.
I acknowledge I'm clearly in no position to evaluate this
design. I have been knocking around it for long enough to have
no idea how easy it is to get into it from the outside, or how
good it is. By all signs I could gather this feels like good
design, and one of the best I've ever put together. The
allocators defined have an archetypal feeling, are flexible
both statically and dynamically, and morph and combine in
infinite ways.
CAllocator and CAllocatorImpl make the link between the static
and dynamic worlds. Once an allocator is assembled out of
pieces and finely tuned, wrapping it in a dynamic API is a snap.
Please destroy! I've literally sweat as I'm sending this :o).

I'm nowhere near experienced enough to comment on how good this
really is, but it sure looks like an impressive design.
Congratulations :)
