I believe the use of tagged pointers has been considered and so far rejected by the CPython developers. And no one else that I know of has developed a fork for that. It would seem more feasible with 64 bit pointers where there seem to be spare bits. But CPython will have to support 32 bit machines for several years.
I've seen that mistake made twice (IBM 370 architecture (probably 360 too, I'm too young to have used it) and ARM2/ARM3). I'd rather not see it a third time, thank you.
