import std.getopt;

void main(string[] args)
{
    int i;
    getopt(args, &i);
}

std\getopt.d(392): Error: array index [1] is outside array bounds [0 .. 1]
std\getopt.d(401): Error: string slice [2 .. 1] is out of bounds
std\getopt.d(401): Error: cannot return non-void from void function
std\getopt.d(351): Error: template instance std.getopt.getoptImpl!(int*) error
instantiating

I think we can fix this easily:

before:
void getopt(T...)(ref string[] args, T opts) {

after:
void getopt(T...)(ref string[] args, T opts) if (T.length > 1) {
