I agree.  We need soem syntax to specify address space literals.
I might suggest '@' followed by an address-space name.  (I'm
not sure if this conflicts with the array "repeat" operator.)

0x12345678@i

0x12345678@d

More generally:
        integer-expression @NAME
coerces the integer to a pointer in the named space.

This syntax could also be used for output.
