Actually, there is a much more natural and powerful way to handle this in D:
one of the nicer things about C is the way you can get letters out of strings
by doing things like:

     "abcdefghijklmnopqrstuvwxyz"[letter]

Why not extend this and allow in-line arrays?  This would allow the "choose"
operator to work as, for example:

    array int {x1, x2, x3, ...}[i]

This of course means that "abc" is exactly the same as 

    array char {'a', 'b', 'c', '\0'}


. . . just another silly idea.
