After some reading through the whole thread I think his "$ idea" can
only be applied to a RandomAccessRange (and similar) where the size can
be known...
It already works with a RandomAccessRange:
void main()
{
auto a = [1, 2, 3, 4];
auto b = a.map!(x => x + 1);
writeln(b[$-1]);
}
It's just that the compiler can't reach into the body of another
function to determine what variable you're talking about to find the
correct value to pass.
