Clean up asm code a bit. - Use vector instead of Array, reducing allocations. - Use vectors instead of deques since we only push_back and index. - Remove redundant typedefs of iterators. - Comment out unused variable (used only in commented-out GDC code). - A few whitespace changes.

module foreach1;
extern(C) int printf(char*, ...);

void main()
{
    static arr = [1,2,3,4,5];

    printf("forward");
    foreach(v;arr) {
        printf(" %d",v);
    }
    printf("\nreverse");
    foreach_reverse(v;arr) {
        printf(" %d",v);
    }
    printf("\n");
}
