Perhaps because back in 1990 I wrote a C interpreter for embedding into applications which did pretty much what Cheri does -- under the hood, pointers had an associated base address and range and other metadata, and the VM that ran the bytecode checked all pointer dereferences and pointer manipulations to ensure they didn't scribble outside the lines. I would expect such things to become even more common going forward. -- Ian
