I'm not sure.  Of course, pending a real solution from someone who knows better, you could 
do this:

# void main () {
#   int[] array             ;
#   auto  ptr   = array.ptr ;
#
#   asm {
#     mov  EAX , ptr ;
#   }
# }

Any reason why you can't make the index inout?  I've done it often enough myself to this 
very effect.  Of course, I'm sure its undefined behavior with associative arrays, but with 
fixed/variable-length arrays it works just fine.

# int[] arr = someBigFunction();
#
# /* skip any values preceded by 0 ... for some reason */
# foreach (inout i, inout x; arr) {
#   if (i == 0) {
#     i++;
#     continue;
#   }
#   /* do stuff with x */
# }
