Since `kernel` is a `Tuple`, you can only access it with
compile-time constant indices.
But your loop variable `i` is not a compile-time constant, it's
being calculated at run time. What's more, it depends on
`results.length` which is also not a compile-time constant. But
`results.length` is the same as `kernels.length`. And being the
length of a `Tuple`, that one is a compile-time constant.
So you can rewrite your loop as a `static foreach` (which is
evaluated during compile-time) using `kernels.length` instead
of `results.length`:
static foreach (i; 1 .. kernels.length)
{
results[i] = bench(kernels[i], n, verbose);
}
Thank you very much. I though that if I used a `static foreach`
loop D would attempt to run the calculation `bench()` at compile
time rather than at run time but it doesn't which is good. So
`static foreach` allows you to index at compile time and if its
scope runs at run time it is run time and if at compile time it
is compile time evaluated?
