   I don't see what you're getting at here.  It's far preferable to isolate   
   the unsafe operations to a few places in the program, than to have them   
   pervading the code base.  E.g. you can't really write a garbage   
   collector without dealing with memory addresses, but if the GC is part   
   of a Lisp interpreter, the user's Lisp program doesn't have to be able   
   to see the raw addresses.
