I don't agree. I've done ISRs and memory mapped I/O. The actual piece of 
code that accessed the data that way formed a miniscule part of the 
program, even on programs that were completely interrupt driven (like I 
wrote an ASCII terminal program). Those are well served by two lines of 
inline asm or a compiler builtin PEEK and POKE function.

Building a whole volatile subsystem into the type system for that is a 
huge waste of resources.
