Frankly, I was still hoping we could experiment a bit with "alternative pointers" within the current ABI without adding completely new headers... Anyway, in case we (you) want to pursue this approach, want to propose a prototype along these lines, a specific framework is already available. The G++ front-end implements this C++0x feature:

which is already successfully used for the debug-mode containers and the parallel-mode algorithms.

Thanks,
Paolo.
