I agree. I think just "a[n]". Then you can use it for things like 2-element
arrays that hold positions, but not for referencing fields in structures. The
latter can be handled via new globals which contain the address of the field
in question, and the "*" syntax.

PS, Nick Rees was unkind enough as to enquire if this will be implemented
    before or after the macro library. The answer: before!
