Variable "i" can not be read at compile time

[data pulverizer]

Hi all,

I'm getting the error:

```
Error: variable i cannot be read at compile time
Error: template instance 
script.runKernelBenchmarks!(Tuple!(DotProduct!float, 
Gaussian!float, Polynomial!float, Exponential!float, Log!float, 
Cauchy!float, Power!float, Wave!float, Sigmoid!float)) error 
instantiating
```

When I run ...

```
...
auto runKernelBenchmarks(KS)(KS kernels, long[] n, bool verbose = 
true)
{
   auto tmp = bench(kernels[0], n, verbose);
   alias R = typeof(tmp);
   R[] results = new R[kernels.length];
   results[0] = tmp;
   for(size_t i = 1; i < results.length; ++i)
   {
     results[i] = bench(kernels[i], n, verbose);
   }
   return results;
}

void main()
{
   alias T = float;
   auto kernels = tuple(DotProduct!(T)(),   Gaussian!(T)(1), 
Polynomial!(T)(2.5f, 1),
                        Exponential!(T)(1), Log!(T)(3),      
Cauchy!(T)(1),
                        Power!(T)(2.5f),    Wave!(T)(1),     
Sigmoid!(T)(1, 1));
   string[] kernelNames = ["DotProduct",  "Gaussian", "Polynomial",
                        "Exponential", "Log",      "Cauchy",
                        "Power",       "Wave",     "Sigmoid"];
   long[] n = [100L, 500L, 1000L];
   auto results = runKernelBenchmarks(kernels, n);
   writeln("Results: ", results);
}
```

Thanks
