Hmmm, why hasn't anybody just suggested doing this?  It seems to work
fine in dmd.

    auto
        x = 23.5,
        y = 14,
        z = y*x,
        s = "foo",
        w = z * s.length;

OR

    immutable
        x = 23.5,
        y = 14,
        z = y*x,
        s = "foo",
        w = z * s.length;
