           Summary: Cannot use int from tuple as an index

An int in a tuple cannot be used as an index for a tuple, even if it is
completely determined at compile time.

---------------------------
// This doesn't work
template Nth(TList...) {
    const int N = TList[0];
    auto Nth = TList[N];
}
void main()
{
    writefln( Nth!(1,"hi","there") );
}
-------------

In this case the sample can be fixed by using:

   template Nth(int N, TList...) { 

But that's not always the case.
