Oh, I forgot to mention. Back in the 16 bit days, I invented something called a 
"handle pointer".

http://www.digitalmars.com/ctg/handle-pointers.html

It was a special pointer type that was dereferenced through a function call. The 
particular implementation of it was to enable to use bank-switched EMS memory as 
if it were regularly addressible memory.

In D this would be better off making the special pointer types a user defined 
struct type. Compiler support isn't necessary.
